Geological disasters types and prevention measures of Chengdu metro construction

在总结已建地铁工程经验的基础上,结合在建和拟建工程实际,指出成都地铁工程建设可能引发和遭受的地质灾害类型主要有地面与地基基础沉降,边坡变形、坍塌、滑移,砂土、粉土地层液化,并针对其地质灾害类型提出相应的工程防治和监测措施,以避免工程建设中地质灾害的发生或减小地质灾害所造成的损失。

On the basis of summing up built subway engineering experience, combining with in build and plan to build project, pointed out may be triggered and subjected to geological disasters types in Chengdu metro construction mainly had ground and foundation settlement, slope de- formation, collapse, landslide, sand soil, power ground layer liquefaction, and put forward corresponding engineering prevention and monitoring measures considering the geological disasters types, in order to avoid geological disasters in construction or reduce the losses caused by geological disasters.
