桩筏基础的实用优化设计体系

Practical and Optimizing Design System of Piled Raft Foundations

介绍了目前桩筏基础的设计现状,从设计思路、筏板的设计和桩的设计三方面阐述了工程设计中用到的各种方法,并比较分析了其利弊,指出当前桩筏基础设计方法存在系统性差、实用程度低、缺乏优化设计、没有承载能力极限状态与正常使用极限状态设计思想等问题,并针对这些问题提出了应对措施。

The paper introduced current design status of piled raft foundation.Based on de-scribing various methods used in engineering design from three respects,including design idea,de-sign methods of rafts and piles,the advantages and disadvantages of each method were analyzed,and some problems of the current design methods were pointed out,such as poor systematization,practicability and optimization,no consideration about the limit states of carrying capacity and nor-mal use,and so on.Furthermore,some countermeasures were proposed.
