摘要
随着建设活动的日益频繁以及建筑范围的扩大,局部表层岩溶被揭露,出现不同于基坑整体失稳的局部岩溶充填物的失稳现象,此失稳现象往往和地下岩溶水相联系,因为处于局部,不能引起设计人员的重视,在沟槽中岩溶水动力的作用下失稳,可能产生较大的工程问题。
As the frequency of construction and enlargement of construction scale,local part karst was exposed,the instability phenomena of local karst substance which different with the whole instability of foundation.This kind phenomena always has relation with underground karst water.For the local position,it can＇t raise the attention of the designer,the instability by the groove karst water power may cause big engineer problem.
