周边开挖对已有建筑地基承载力的影响分析

摘要

According to the derivation process of Prandtl foundation bearing capacity,the paper deduces the decreasing value calculation formula of existing architectural bearing capacity under the condition of surrounding excavation.Integrating with the engineering practice,it proves the rationality of the calculation method,which has certain guiding meaning for similar engineering.%根据普朗特地基承载力推导过程,导出了周边开挖情况下,已有建筑地基承载力减小值的计算公式,结合工程实践,证明计算办法的合理性,对类似工程具有指导意义。
