穿越复杂溶洞地质桩基稳定性分析

摘要

考虑穿越复杂岩溶地质桩基的实际受力情况,提出假设,建立桩基承载力计算简化模型,并提出桩基承载力计算公式;最后基于实际工程,分析了相关参数对穿越复杂岩溶地质桩基稳定性的影响,得出桩径的影响最为显著的结论。%Considering the factual stress situation for the pile foundation of crossing complicated karst geology,the paper points out the hypothesis and establishes the simplified model of the calculation for the pile foundation＇s bearing capacity,points out the calculation formula for the pile foundation＇s loading capacity,finally,based on the actual project,analyzes the influence of the relative parameter on the stability of the pile foundation crossing complex karst districts,and concludes the influence of the pile diameter is more obvious.
