摘　　要：简述水闸稳定破坏常见形式、整体稳定验算常规方法,介绍稳定计算公式蕴含的地质基本理论。通过几个经典土力学理论公式特征比较和计算成果对比,阐述汉森公式承载力计算考虑的影响因素、相关处理方法和使用限制条件,讨论该公式计算成果和稳定结论的可靠性。针对地基均匀性限制条件,通过与原位测试成果对比分析,说明汉森公式计算夹软弱土地基承载力基本取值原则,补充规范认可的其他方法。This paper briefly introduces the common form of sluice stability failure, the routine method of overall stability checking, and introduces the basic theory of geological. Through several classical soil mechanics theory formula feature comparison and calculation results, expounds the Hansen formula of bearing capacity calculation in consideration of influencing factors, processing methods and use conditions, discusses the formula to calculate the reliability of the results and conclusions are stable. Uniformity of constraints for foundation, through the comparison analysis and in - situ test results, Hansen formula calculation principle of basic value of bearing capacity of soft soil foundation, added the specification approved by the other methods.
