Discussion on safety grades of retaining and protection structure design for excavations in Fujian

针对现行国家《规范》、《规程》与现行福建地方《规范》在基坑结构设计安全等级确定方面存在的差异问题。通过相关条文的对比分析,说明了差异存在的原因以及地方《规范》对国家行业《规程》进行量化后产生的不利问题,提出了确定安全等级的具体方法。

Differences of safety grades of retaining and protection structure design for excavations in current national＂standard＂,＂Regulations＂and the current Fujian local＂standard＂were discussed.By analysing the relevant provisions,the causes of the difference and the adverse problems after Fujian local ＂standard＂quantified national ＂standard＂were analysed.
