Bridges, Tunnels and Their Relationship to the Economic Development on Both Sides of Taiwan Strait

The construction of bridges and tunnels plays an important role in the social and economic development of cities and local regions. The planning of the bridge and tunnel across Taiwan Straits will have a positive effect on the economic development at each stage: preplanning, engineering construction, and the completion of the project. The two sides of Taiwan Straits have the advantage of a suitable location, consanguineous relationship, and appropriate geographic conditions. Currently, there are many economic and cultural communications between both sides of the Straits. The bridge and tunnel from Xiamen to Jinmen can be regarded as the beginning of the “golden link belt.” The total capability for sustainable development of Fujian Province ranks the sixth among 31 provinces in China, which will provide powerful support for the construction of the bridge and tunnel.

Modern Undersea Tunneling Technology and the Undersea Tunnel across Taiwan Strait

It is necessary to construct the undersea tunnel across the Taiwan Straits because it would help strengthen communication between Taiwan and the mainland, promote economic and cultural exchanges, and uphold national unification and territorial integrity. Nowadays, there are many undersea tunnels in the world; the English Channel Tunnel and the Seikan Tunnel are two of the most famous. Rich experience has been obtained during the exploration, surveying, design, construction and operation of these undersea tunnels. So, technologically, it is completely feasible to construct the undersea tunnel of the Taiwan Straits. The total length of the undersea Taiwan Straits tunnel is about 220?km; however, water along most of the proposed tunnel site, is less than 50?m deep and the geological condition of the site is relatively good. Although technical difficulties exists in design and construction, there are some favorable aspects. It is, therefore, necessary to start a study by launching some exploration surveys and collecting related data.     

An Engineering Concept of the Taiwan Strait Tunnel

The necessity and the preliminary tentative plan for the construction of the undersea tunnel across Taiwan Strait are expounded in this atricle. The strait undersea tunnels, which have been built and investigated in the world, and their engineering characteristics and construction methods have been introduced herein briefly. Taiwan has been a part of China since ancient times and the people between the mainland and Taiwan are kindred compatriots in the extended family of the Chinese multinational country. For a long time, the people between southeast of China and Taiwan have had frequent communication in economy and culture. With the progress of times and the need of development, it has been put forward to build a safe and reliable undersea tunnel that is not affected by the environment across Taiwan Strait, and one which is also a magnificent project for the China in the long-term. Whether by using a bridge or an undersea tunnel or both across the strait is a problem worthy of further research. According to such conditions as the weather of Taiwan Strait, depth of water, undersea terrain, possibility of engineering and hydrological geology under the sea, as well as the possibility of Taiwan Strait as a main shipping passage from south to north of China and the experience of existing passage across strait in the world, the primary analysis shows that the scheme of an undersea tunnel should be considered. Therefore the concept of the undersea tunnel engineering across Taiwan Strait is introduced in detail here.     

Major Features of Topography, Geology, and Crustal Stability in the Taiwan Strait: A Scientific Approach to the Problem of the Taiwan Strait Tunnel Project

This article discusses briefly the major features of topography, geology, and crustal stability of the possible Taiwan Strait Tunnel Project (TST Project) area. Any one route of the conceived TST Project is larger than either of the English Channel Tunnel or the Seikan submarine Tunnel (Japan) by at least three times in length, and the topographic and geologic conditions are rather more complex and complicated than those of the former two projects. Moreover, the Taiwan Strait is a seismic risk area. Hence, the selection of the route of the submarine tunnel should take advantage of the favorable conditions in the topographic, geologic, seismologic, and other fields to avoid the unfavorable circumstances. At the end of the article, two supposed by comparable routes, especially the south one of TST Project are discussed.

Protection, Pollution Prevention and Control of Environment in Construction Stage

The proposed Taiwan Strait Tunnel will raise numerous challenges for environmental professionals. The environmental issues must be incorporated in the preliminary study, planning, design, and construction of the works and be addressed consistently throughout all phases of the project. In this article, the environmental issues that will be encountered in the construction stage are discussed, including environmental impact assessment, environmental monitoring, and specific environmental issues during construction such as spoil handling, air quality and noise control, drainage, and health and safety. The experience and practice of handling environmental issues during the construction English Channel Tunnel are reviewed throughout the discussion.

A Feasibility Study on the Application of Fiber-Optic Distributed Sensors for Strain Measurement in the Taiwan Strait Tunnel Project

Taiwan Strait Tunnel (TST) will be an extra-long tunnel or tunnel-bridge complex, running over 150 km of seafloor geologic body with complicated topographic and geologic units. It is therefore necessary to measure and monitor the strain distribution along the TST. In this article, the Brillouin optical time-domain reflectometer (BOTDR), a newly developed strain measurement and monitoring technology, is introduced, and the feasibility of its application in the strain monitoring for TST is analyzed through the monitoring achievement with BOTDR of a tunnel located in Nanjing City, China. The results indicate that the BOTDR has many unique merits such as distributed measurement, long-distance, real-time, and resistibility for strain monitoring application in a tunnel such as TST. Finally, apreliminary scheme for BOTDR application in TST monitoring is proposed.

Environmental Geotechnical Problems in the Taiwan Strait Area

This article presents general information on environmental geotechnical problems along the Taiwan Strait Tunnel (TST) route including sea-floor characteristics. The term apparent sea-floor is introduced. This layer is due to land erosion washing down and settling in the Taiwan Strait. The depth of ocean water along the Taiwan Strait is estimated. Various soil, and rock types and marine sediments along the coastline of mainland, Taiwan Strait, and Taiwan Islands are presented. Foundation problems under adverse marine environments are discussed.

渤海海峡跨海通道建设对城市经济联系的影响分析

渤海海峡跨海通道建设将极大改变环渤海乃至整个东部沿海的交通格局,势必对其目标城市大连、烟台带来直接的经济影响,同时也会对辽东半岛、山东半岛乃至东北、华北和华东不同尺度地区的经济联系产生深远影响。文章选取山东省17个和辽宁省14个地级市的地区的生产总值、城市人口以及城市间的最短时间距离等指标,测度渤海海峡跨海通道建成前后,对山东、辽宁两省区域城市经济联系的影响。研究表明:渤海海峡跨海通道建成后,对大连、烟台间的经济联系强度有显著提高,各城市经济联系度的平均增幅明显不同;同时,受距离衰减规律的影响,两省的城市分别以大连、烟台为中心,根据距离远近及城市自身发展程度分为4个层次,经济联系强度由内向外逐层次减弱;从整体上看,渤海通道的建设对带动两省城市之间的经济联系度都有大幅度提升。     

台湾海峡及其两岸地震和地热特征

本文主要论述了台湾海峡及其两岸地震和地热的各自特征以及它们之间的关系。该地区的4个北东向地震带刻划了各个块体的相互关系。台东地震带的震源机制解表明台湾纵谷具有复杂的过渡性构造。台湾西部和台湾海峡的地震活动也受到菲律宾海板块的控制。福建沿海的地震活动与巴士断层活动有关。在自东向西各地震带的活动能量急剧下降的同时,相应的地热流异常值有一个上升趋势,海峡西岸的地热异常高值多分布在NE与NW向断裂的交汇点上。
