摘要
针对独立基础和条形基础的软弱下卧层的验算,规范给出具体方法;而对于带地下室筏板基础的软弱下卧层验算,因涉及开挖过程的应力历史,规范未有明确计算方法。文章旨在讨论带地库的筏板基础软弱下卧层的计算方法。结果表明,针对独立基础的公式用于筏板基础,同样有效。
For the checking calculation of the soft substratum of independent foundation and strip foundation,the specific method is given in the specification;for the checking calculation of the soft substratum of raft foundation with basement,there is no clear calculation method in the specification because it involves the stress history of excavation process.This paper aims to discuss the calculation method of the soft substratum of raft foundation with basement.The results show that the formula for independent foundation is also effective for raft foundation.
