高层建筑桩、筏基础共同作用沉降分析计算

Calculation of the Settlement Under Highrise Buildings by Pile-raft Foundation Interaction

某高层建筑场地基岩裂隙发育,软弱夹层分布复杂,强风化、中风化、微风化岩带交互叠夹,通过基础的优化设计,最终确定基础采用桩、筏共同作用的混合型基础形式,解决了基础设计的难题,采用非均质地基刚性基础的变形计算方法计算的楼房沉降值与实测沉降很接近。

In the site of highrise buildings, the development of joint foundation rook is weak and the interbedded distribution is complicated. Strong-weathered layers, moderate-weathered layers and slightly-weathered layers are interbedding. The mixing foundation mode of pile-raft foundation interaction is determined by optimum design. The method of calculating the deformation of inhomogeneous rigid foundation shows that the building settlement approximates to the measured settlement.
