摘　　要：目前国内对管道地基承载力的研究甚少,导致了在实际工程中出现取值统一化的现象。由此,基于地基承载力的基本概念和相关规范要求,通过简化推导出的开槽施工的管道基底压力计算式,分别对比分析了管径、管道覆土厚度、地下水位和地面荷载对管道基底压力的影响。该研究成果为设计人员能够更合理地设计管道地基承载力提供了依据和建议。Due to few research on the subsoil bearing capacity of pipeline currently in China,values is unified in practical engineering.Base on the basic concepts of subsoil bearing capacity and the requirements of relevant speci-fication,the effects of pipe diameter,thickness of soil covering,groundwater level and ground load on base pressure of pipe were compared and analyzed by the deduced calculation formulas of excavated construction.The basis and suggestions are put forward to design more reasonably.
