同位素技术在某核废处置场区水文地质条件研究中的应用

本文通过对研究区各类地下水化学成分、水中氢、氧稳定同位素及放射性同位素的研究，区分出浅层地下水（孔隙水）和基岩风化裂隙水。确定了地下水的补给区为排牙山区；地表水、地下水迳流的主要方向为ＳＥ向，同时存在地下水侧向迁移，并以泉的形式补给浅层水和地表水。通过氚的衰变计算及与香港观测站的资料对比，确定了区内地下水的相对年龄，并将其分为３个年龄组：（１）迳流时间最短的地下水，具近期大气降水的氚浓度；（２）相对年龄为２０年左右的浅层地下水；（３）相对年龄大于３０年的低氚水。     

烈度计台站远程监控系统

烈度计台站在地震预警中具有重要作用，对烈度计台站的远程监控是保证观测数据稳定可靠的前提。针对现有监控系统无法对台站供电、网络、设备状态等信息进行智能监控的问题，设计烈度计台站远程监控系统，实现对台站供电、网络、I/O开关量、烈度计状态等信息的采集及远程控制等功能，并在天津烈度计台网进行部署，提高了故障排查及维护效率，保证了烈度计台站数据的连续率。     

Geostatistical method to delineate anomalies of multi-scale spatial variation in hydrogeological changes due to the ChiChi earthquake in the ChouShui River alluvial fan in Taiwan

This study uses Ordinary Kriging (OK), Sequential Gaussian Simulation (SGS) and Simulated Annealing Simulation (SAS) to relocate the completely heterotopic dataset from the locations of the Standardized Satellite Oriented Control Point System (SSOCPS) stations to the Groundwater Monitoring Networks (GMNS) stations and factorial kriging to analyze and map relationships among seven variables, including the hydraulic conductivities of three aquifers, the vertical displacements of the ground and groundwater level changes in the wells of three aquifers, and also to delineate the anomalies of multi-scale spatial variation of hydrogeological properties associated with the ChiChi earthquake, measuring 7.3 on the Richter scale, in the ChouShui River alluvial fan in Taiwan. In this study, the anomalies of spatial variation of hydrogeological properties associated with the earthquake are illustrated at micro, local and regional scales of 9, 12 and 36 km, respectively. In the study area, regionalization components associated with variation at local and regional scales are obtained and mapped by factorial kriging. Factorial Kriging Analysis (FKA) also demonstrated that the main effects of the ChiChi earthquake on the spatial variations of groundwater hydrological changes include porous media compression at micro scale, hydrogeological heterogeneousness of the sediments within the aquifer at local scale and the cyclic loading of deviatoric stress at regional scale. Finally, maps of spatial variations of regional components fully depicted all of the anomalies of spatial variation of hydrogeological changes due to the ChiChi earthquake and can be used to identify, confirm and monitor the hydrogeological properties in this study area.     

Seepage problems in the right abutment of the Shahid Abbaspour dam, southern Iran

In this study, seepage phenomena through the right abutment of Shahid Abbaspour dam are investigated. The Shahid Abbaspour dam is a 200 m high arch dam, which regulates the waters of the Karun River, serves power generation, and flood control and irrigation needs. The dam site lies in the Zagros Mountains of southern Iran. This region presents continuous series of mainly of karstic limestone, marl, shale and gypsum ranging in age from Jurassic to Pliocene. The region has subsequently been folded and faulted. Seepage from the Shahid Abbaspour reservoir occurs mainly through the karstic limestone.The basic foundation treatment of the dam consisted of consolidation grouting, a high-pressure grout curtain and a drainage curtain. Moreover, a 144 m high and 30 m wide concrete cutoff wall was built to prevent reservoir seepage through a clay-filled fracture zone in the right abutment. The grout curtain penetrates the “Principal Vuggy Zone” only beneath the central portion of the dam and below the cutoff wall. In the right abutment fan curtains were constructed to reduce drainage flows, but the seepage problem could not be solved. In order to determine the seepage direction and karstification pattern, hydrogeological studies have been carried out. Additional investigation boreholes have been drilled to monitor fluctuations in groundwater level. Besides these, water chemistry, dye tracer, pinhole and XRF tests have been carried out. As a result of these studies, seepage paths have been identified in the karstic limestone in the right abutment of the dam.

恶劣气象条件对高速公路安全运营的影响及防治对策研究

恶劣气象条件引发的高速公路交通事故,往往比其它原因引发的高速公路交通事故要严重的多。防治恶劣天气对高速公路安全运营的影响,涉及到高速公路管理部门、交警和气象部门,所以应当按照“部门之间协调配合,互为补充”的原则,积极探索高速公路安全运营应对恶劣气象条件的防治措施和途径。     

江淮地震区的地震活动性研究

江淮地震区是以５－６级地震为主的中强地震活动区,其地震活动存在百年尺度和数十年尺准周期性,中强地震活动存在东移和逆时针迁移二种运动,１９９０年以来本区与华北及华南地区的交界带地震活跃。根据以上分析贝斯估计、地震复发的条件概率预测、下世纪初可能发生６级左右地震,位置估计在本区东部的南黄海海域,苏、皖交界也有发生中等以上地震的可能。

天时、与中国历史（Ⅱ）：“好（坏）天时”与历史上的“顺（乱）世”

中国历史上的“顺世”绝大多数（≈83％）出现在“好天时纪”中；绝大多数“乱世”出现在“坏天时纪”内（≈85％）。历史上的分裂期都出现在“长坏天时纪”中。依据“天时好、坏”与“顺世、乱世”的两两对应关系，可将历史上的皇帝分为贤、明、庸、暴四类。本世纪初开始的“长好天时纪”可能是中华民族又一个辉煌时期的开始。但是对“坏天时代”的可能干扰，应引起足够重视。     

Description of Ecosystem of the Lower Odra and the Odra Estuary

Environmental conditions of the lower river Odra and its estuary show a high variability of chemical and biological parameters, related to the dynamics of the river, its mouth area, the Lake Dabie-Szczecin Lagoon system, and the Pomeranian Bay. Water chemistry, affected by the total sum of industrial, urban, and agricultural pollution discharged from the direct drainage area is discussed. This pollution load influences the composition and ecological structures of terrestrial, frequently unique, phytal communities associated with aquatic areas, phyto- and zooplankton, benthos, fish fauna, and avifauna. The current status of the terrestrial and aquatic ecosystems is described; elements of cultural infrastructure existing within the Lower Odra Valley in Western Pomerania are mentioned as well.
