【摘要】 中国正在快速、大规模地开展基础设施建设。确保重大工程安全对于这些基础设施建设具有重大意义。该文从以下5个方面论述开展重大工程安全相关科研工作的重要意义和必要性:(1)不断挑战极限的工程建设指标(如坝高、桥梁跨度、高铁时速)孕育的风险;(2)相当一批基础设施步入其生命周期的中、老年阶段面临的问题;(3)新兴的基础设施建设领域尚需积累经验;(4)严重的自然灾害给全面建设小康社会带来的大挑战;(5)城镇化建设进程带来的公共安全隐患。该文回顾了在能源、矿山、交通、城市高层建筑等领域基础设施建设有关安全的主要技术问题,同时讨论了关于可靠度分析、强震地区抗震设计、减灾和信息支持方面的重大科学问题。更多还原

【Abstract】 China is undergoing rapid and large scale infrastructure development. Construction safety is of paramount importance in this movement. The authors address the following aspects that bring great impacts on construction safety of major infrastructures:( 1) the risks involved in a continuous record-breaking engineering practice such as the dam height,bridge span,and speed of trains,etc.;( 2) the large number of engineering projects at the aging period of their life cycle;( 3) new disciplines of infrastructures with limited experience of safe construction and maintenance;( 4) serious natural hazards against the effort of establishing welfare societies; and( 5) risk potentials in China’ s urbanization process. This paper provides a framework for improving safety performance on major construction projects in the coming years in China. It covers the key technological problems involved in the infrastructure development of energy resources,mining,transportation,metropolitan high rising buildings,etc. Special attentions have been paid on the areas of reliability analysis,aseismic design in strong earthquake prone zones,hazard mitigation approaches and informationbased safe construction.更多还原
