LABORATORY MODEL LOADING TEST OF RAFT FOUNDATION
-
摘要: 随着高层建筑的增多,在高层建筑基础工程的设计中引入考虑地基土的非线性性状的设计方式,已显得尤为重要。通过筏基的室内模型载荷试验,得到了土体受荷所产生的非线性性状的一些规律,对筏基的受荷破坏过程有了一定的认识。Abstract: With the increase of the amount of high-rise buildings,it is shown that introducing the soil nonlinear behavior into the foundation design is very important.In this paper,the nonlinear behavior of soil in loading state is described and analyzed.By which, a certain understanding of the failure process of a raft foundation is obtained.
