桩基础软弱下卧层验算模型的探讨
Discussion of the calculation formula about superimposed load of the soft underlying stratum in the group pile foundations
【摘要】 在桩端持力层强度验算和软弱下卧层验算模型统一的基础上 ,结合工程实例 ,对建筑桩基技术规范中有关软弱下卧层附加应力计算公式的简化问题进行了分析和讨论 ,并提出了修正后的验算公式 ,对工程实践具有指导意义
【Abstract】 On the base of piles tip supporting course strength calculates and soft underlying stratum, the problems about the calculation formula of the soft underlying stratum in the Technical Code for Building Pile Foundations are analysed and discussed combining the case history, and the correct calculation formula is put forward. The conclusions are useful for engineering practice.
