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。 Pumping caused land subsidence, resulting in uneven settlement of the foundation of the building has become an important environmental disaster in the construction of the project. In this paper, indoor experiments were carried out to test the clay and sandy soil under different combinations. The settlement of the soil sample was observed and analyzed. The ground subsidence caused by pumping and the different soil types under different pumping conditions were studied. Effect of Layer Order on the Law of Ground Subsidence.
