Design discussion on the raft foundation of a high-rise building under the condition of complex geology
There are extensive granite residual soil distributed in southern Fujian.The bearing capacity value of granite residual soil has a good space to improve because of the particularity of its soil layer.This paper take the example of raft foundation under the condition of complex geology of a high-rise building in Xiamen.Through the analysis of residual sand clay soil characteristics,the feasibility of using raft foundation is demonstrated from the aspects of bearing capacity buried depth correction,settlement amount and settlement difference,as well as the risk prediction of using raft foundation and the strengthening measures that can be taken.It hopes to provide reference in sim-ilar projects for designers.
