本文对桩筏基础进行了竖向受荷分析,对于目前一般采用的均匀布置的桩基础,文中用Lagrange乘子法对桩位进行优化,以期得到最合理的桩位布置,使基础的不均匀沉降尽可能小,并减小条基或筏板的弯矩。
In this paper, vertical load analysis is performed on piled raft foundation. For the commonly used uniformly-arranged pile foundations, the Lagrange multiplier method is used to optimize the pile position in order to obtain the most reasonable pile placement and make the foundation uneven. Settling is as small as possible and reduces the bending moment of the foundation or raft.
