摘　　要：气候异常对山区工程建设与运营已造成严重影响,同时也给山区工程建设与运营安全提出了新的挑战。分析了降雨、异常温度等异常气候对山区工程建设与运营环境造成的影响,认为异常气候将改变工程材料的结构与力学参数,以及工程的服役环境,而且异常气候对工程的耐久性、受力性能等方面的影响也不可忽视。在此基础上,从防灾、减灾等方面给出针对当前异常气候背景需要进一步研究的科学问题,并指出工程建设在设计标准、结构物理力学参数、安全评估系统等应对气候变化方面的对策和建议。Unusual climate events have induced severe influences on mountain project construction and operation,and also constitute new challenges to security of mountain project construction and operation. The effects of rainfall,unusual temperatures on environments of mountain project construction and operation are analyzed,and it is concluded that none of these unusual climate events should be ignored in durability and bearing properties because the unusual climate events should change the structure and mechanical parameters of engineering materials,and also change the active environment mountain engineering. Based on the above analysis,to deal with the unusual climate events,the further research scientific problems are put forward from the disaster prevention and mitigation,and countermeasures are proposed for design standards,mechanical parameters,safety evaluation system mountain project construction and operation.
