某深埋长隧地应力演化及围岩应力位移模拟研究

结合西部地区某深埋长大公路隧道信息化施工 ,对深埋长隧地应力演化及围岩应力位移进行了弹塑性有限元数值模拟研究。研究结果表明 ,隧道轴线现代地应力状况与隧道埋深、地层岩性及构造发育程度有关 ,最大地应力为40 0MPa左右 ;隧道周边围岩应力在曲边墙底部最大 ,约 3 8 0MPa ,隧道开挖引起的围岩应力影响范围约 2 5 0m ;隧道水平收敛和拱顶下沉位移与隧道埋深近于成直线关系。这些研究结果为深埋长隧信息化设计和施工以及围岩稳定性分析提供了科学依据。     

地理信息技术的发展与应用

地理信息系统是国家信息资源的重要组成部分。地理信息技术经过20多年的飞速发展，已经渗透到社会各个方面，促使人们生产、生活方式发生深刻变化。我国地理信息系统(GIS)技术正在向信息化方向发展，并正在逐步成为面向21世纪的支柱产业一信息产业的重要组成部分。国际GIS技术的发展趋势，主要体现在两个方面，一是综合，二是分化。从空间信息处理的角度看，可将GIS的发展分为空间信息的管理、分析、模拟和调控四个阶段。GIS技术的应用表现在一是面向大型项目，二是面向公众。     

关中盆地水资源可持续开发利用对策研究--以渭南市为例

以关中盆地东部的渭南市为例，概述了水资源的分布特征及其开发利用现状。认为水资源开发利用中存在水资源浪费严重，重复利用率低；行政区块限制，水资源调配不够；不合理开采地下水，出现负环境效应；地下水人工调控力度不够，不能有效的促进生态环境良性循环；对地下水资源的研究、规划和管理滞后等五个方面的主要问题。针对存在的主要问题，提出了六项水资源可持续开发利用对策，包括节水对策、开源对策、改水对策、调水对策、增补对策以及管理对策。     

Devolution, the governance of regional development and the Trade Union Congress in the North East region of England

The devolution and regionalisation of political and administrative structures following the election of New Labour in 1997 have changed the nature of the state and territorial development and governance in the UK. A regional and sub-national tier has opened up within the existing multi-layered governance system operating at the supra-national, national and local scales. This ‘new institutional space’ is increasingly open to the participation of social institutions--including trade unions--in economic and social governance. Drawing upon empirical analysis of the experience of the Northern Trade Union Congress (NTUC) in the North East region of England, the paper argues that the NTUC--in contrast to its national organisation--is beginning to engage with the emergent institutional structures but its role is inhibited by the centralised strategy and structure of the TUC nationally, its own need for upgrading, capacity building and greater financial resources and the interaction between the North East’s particular legacy of tripartite corporatism and the more pluralist modes of regional development governance emerging in the English regions. Unless such issues are addressed regional trade union centres--such as the NTUC--risk remaining relatively junior partners in the emergent regional governance structures.     

Urban land transformation for pro-poor economies

The transformation of land into a setting for clustering local economies can become an important cornerstone of poverty policy. This transformation has several functional aspects, which in turn have important institutional and political aspects. Underlying both the functional and institutional factors is the role of local government and local democracy. Such a conceptualization puts to center stage several paradoxes: A terrain that seems “slum-like” turns out to be highly productive and employment generating. Complex tenure forms and mixed land use seen as “unplanned” turn out to be pre-requisites for economic development. There are institutional paradoxes that contrast efforts at “transparency” and managerial “best practices”. Here, the messiness of local bureaucracies in municipal government turns out to be critical for poor groups to influence interventions in their favor. Influencing the public process may be more effective in stealth-like ways rather taking a more visible approach. Most fundamentally these issues remind us that the potential of cities to reinforce or reduce poverty moved far beyond projects and programs and the normative frameworks used by planners and administrators. Instead, it is the transformative process of turning land into economic settings that might be at the center stage. This is a stage where poor groups are the central actors who stealth-like draw on complex alliances across ethnic and class lines to shapes cities in their interests.
