摘要
抽水引起地面沉降,造成建筑物的地基不均匀沉降,已经成为工程建设中的一个重要的环境灾害问题。该文通过室内实验,对粘土和砂土在不同组合情况下进行抽水试验,对土样的沉降情况进行了观察分析,研究了抽水引起的地面沉降问题及抽水条件下不同土体类型、不同成层顺序对地面沉降量变化规律的影响。
Ground uneven settlement of building foundation caused by pumping has become an important en- vironmental disaster problem in the engineering construction. Through the indoor pumping test of clay and sand in different combinations circumstances, the settlement of soil samples is observed and analyzed, finally the ground settlement problems caused by pumping and the influence of change law of ground settlement in differ- ent soil types and different layered sequence by pumping are studied.
