摘要
根据弹性理论平面问题中均布条形荷载作用下附加应力解，建立了计入不同泊松比值的地基容许承载力计算公式。通过分析承载力公式中的泊松比效应，对非粘性土和粘性土进行比较，讨论了相关参数对地基容许承载力的影响，对进行建筑地基基础设计规范修改和工程设计具有理论和工程实际意义。
According to the additional stress solutions of plane problem under the action of uniformly distributed strip load in elastic theory, considering the different Poisson＇ s ratio of ground soil, establish the design formulas for foundation allowable bearing capacity. By means of analyzing the Poisson＇s ratio effect of foundation allowable bearing capacity design formulas, and making the comparison betwween the cohesionless soils and clay soils, discuss the effects of correlative parameters on foundation allowable bearing capacity. It has theoretical and practical application significance in proceeding the modification for design code of building foundation and construction foundation designs.
