基坑支护总体方案的优化与安全问题

Optimization and Safety of Foundation Pit Support Overall Scheme

通过对某深基坑设计方案的探讨,说明基坑支护总体方案优化的方法及应考虑的问题。设计方案从安全因素、施工因素及经济性三方面进行优化,优化后效果良好,提高了安全性,控制了成本,进一步说明基坑支护设计优化的可推广性。

This paper illustrated the method of the foundation pit supporting overall scheme optimization and the problems should be considered through the discussion of a deep foundation pit project. The design scheme was optimized from safety factor, construction factor and economy, the optimized result was good, which increased security and cost control, further, the optimization of foundation pit supporting design could be promoted.
