摘要
从优化设计的角度出发 ,探讨了桩筏基础的设计思路、布桩方式、桩土共同作用等一系列问题 ,得到了一些有益的结论。还提出了一些对设计进行优化的思路和具体方法供读者参考。
Some problems about the optimum design for a piled raft foundation are discussed in the paper. First, design philosophy for a piled raft foundation is studied. A design philosophy is proposed based on the control of settlement. Then, pile arrangement is discussed from the economical point of view. Usually, it is more reasonable to install piles in the middle of a raft foundation. It is also a good choice to install piles under walls or columns. What is more? The bearing capacity of a raft foundation is considered in practical design. Finally, optimum methods for a piled raft foundation are analyzed, and some methods for optimum design are developed.
