岩土工程中的地温应力问题

Problem of Geothermal Stress in Geotechnical Engineering

简介了工程岩体中地温应力影响的认识过程,这是一个未引起广泛注意和系统研究的问题,地壳表层变温带中的温差应力是一些巨大天然地质灾害与工程事故中的匿动力,这一每年再生的匿能是一些岩体工程事故形成机理的一个重要因素。随着我国从建设与运营中的水电工程的系统监测成果中,可分析出地温匿能是形成变形活动的重要原因,也是圆满解释一些工程事故的一把钥匙,在西部大开发中,重视和加强对这一问题的研究很有必要。

The paper presented to recount the process of cognition for the geothermal stress affected the rockmass at the crust that was not taken note with study in all geotechnical engineering subject. Geothermal stress of solar warming layer is a hidden motive force at the big natural geological calamity with some large hydroelectric projects accident. Owing to the hidden power can to regenerate in every year so the mechanism responsible of some geotechnical engineering projects accidents was unknown they're affect. On the basis of the result of the monitoring system in the some civil engineering projects with nature slope can to inspect the major reason by hidden power that is the key to interpret the accident. The major problem of hidden motive force in present large civil projects in west China for a mass of construction development must to be studied emphatically.
