| 摘 要： | 静载试验是目前确定复合地基承载力较为可靠的原位测试技术之一。文章结合某路基软土处理工程实例，分析了由载荷试验确定复合地基承载力的几种常用方法，提出采用相对沉降法来确定粉喷桩复合地基承载力，同时采用双曲线拟合法或回弹法来检验其方法的可靠性，以保证水泥粉喷桩处理软土地基的加固效果。

| Abstract: | Static loading test is one of the reliable in situ test techniques that determine bearing capacity of composite foundation.Combined with one soft clay sub - grade treatment project,this paper detailed analyzes several commonly used meth - ods that determine bearing capacity of composite foundation, advices adopting rel - atively settlement or hyperbola fitting method to determine bearing capacity, and u - ses rebound method to test the results in order to ensure the reinforcement of cement-soil mixed pile. |
