安全系数法与分项系数法在边坡工程中的应用分析

Application Analysis of Safety Factor Method and Component Factor Method in Slope Engineering

以GB 50330—2013《建筑边坡工程技术规范》为依据进行推导计算,建立安全系数法与分项系数法之间的对应关系,从而得出支护结构的验算时,隐式解宜作为标准值,显式解应作为设计值的结论。解决了现行规范中通过安全系数法计算剩余下滑力后,采用分项系数法进行支护结构验算时重复使用安全系数,导致支护结构过大的问题。

Based on GB 50330-2013 Technical Code for Construction Slope Engineering,the corresponding relationship between safety factor method and sub-factor method was deduced and calculated,and the conclusion was drawn that the implicit solution should be taken as the standard value and the explicit solution should be taken as the design value when checking the supporting structure.After calculating the residual sliding force by the safety factor method in the current standard,the problem that the support structure is too large due to the repeated use of the safety factor method is solved.
