受水平拉伸位移作用的地基模拟试验研究

通过使用采动变形模拟试验台进行模拟试验，阐述了在水平拉伸位移作用下，模型的地基顶、底面水平位移之间的对应关系，证实了地基反力不随地基底面不均匀水平位移的变化而变化的规律．这项试验成果，为采动变形模拟试验台的应用打下了基础，为采动（空）区房屋的试验研究工作开辟了新途径．

Studies on Simulation Test of Foundation Under the Action of Horizontal Stretch Displacement

By means of mining deformation simulation test desk, this paper explains the corre sponding relationship between the horizontal displacement producing on the top of model foundation and the horizontal stretch displacement applied to the bottom of model foundation. This paper proves the law that foundation reacting force doesn't vary with the variety of the non-even horizontal stretch displacement applied to the bottom of model foundation. These studies lay a basis for applying mining deformation simulation test desk and provide a new method for test and research works on buildingS in mining areas
