| 摘 要： | 对于非条形浅基础的承载力的求解，目前国内外学者均采用分步单独考虑地基自重影响的求解方法。为求解矩形浅基础地基极限承载力的理论解，首先假定三维地基滑动面，同时考虑黏聚力、超载和土的自重的耦合影响作用，然后在均布荷载作用下根据极限平衡理论，由塑性体的静力平衡条件得到地基承载力计算公式，最后对影响结果的各参数进行了讨论，得出一些有益的结论；通过算例将文中计算公式与几个典型公式计算结果进行了对比分析。验证了文中公式的实用性。

| Abstract: | Scholars at home and abroad calculate the gravity function separately to perform the un-strip shallow footings bearing capacity. The geometry of failure mechanisms is three-dimensional. Cohesion force, overloading and gravity are coupled to calculate the bearing capacity with limit equilibrium theory. Several parameters influencing the calculation result of bearing capacity are discussed. The factors calculated are typically larger than earlier empirical proposals in the literatures. The comparison of results with existing solution is given to validate the method. |
