木里矿区四井田冻土(岩)物理力学性质的研究

冻土因其独特的工程性质成为所有寒区工程面临的一大难题,深入研究和解决冻土问题成为了寒区工程的关键。冻土(岩)测试主要是获取岩土体在冻融条件下,岩土体物理力学性质的变化情况,为露天矿在服务年限内安全开采以及相关设计提供依据。该文主要对木里矿区四井田冻土(岩)物理力学性质从力学参数及地温监测两方面进行研究,为该露天矿边坡稳定的研究做基础。

Permafrost become a major problem faced to all the cold regions engineering because of its unique nature of the works, Indepth study and resolve the permafrost problem has become the key to cold regions engineering.The permafrost （rock）test is to obtain the changes in the physical and mechanical properties of rock and soil when the rock and soil in freezing and thawing conditions and provide the basis for the open pit mine in the service life of safe mining and related design.In this paper, we study the mechanical parameters and ground temperature monitoring of the physical and mechanical properties of the muli mining area four-lda frozen soil （rock）
