【摘要】 针对基坑支护设计中土层参数的选取问题,以悬臂桩支护结构为例,在基坑支护设计中土层参数分别采用分算与合算两种方法计算,结果表明:当各土层差异较大时,采用两种方法计算得出的最大弯矩和埋深相差较大;采用合算的结果较小,分算的结果较大。采用m法对分算与合算的设计计算结果进行悬臂桩的位移和转角的计算,其结果都能满足工程技术相关规范要求。但合算的计算结果更经济,更符合工程实际需要。更多还原

【Abstract】 For choosing soil parameters in retaining and protection of foundation pit design,taking cantilever pile retaining structure as an example,the authors calculated the soil parameters with layered and compounded methods. The results indicate that there is a great contrast between the two results on the embedded pile depth and the maximum moment. The layered result is smaller,while the compounded result is bigger. Using the m method to calculate the displacement and the turning angle. The results is satisfaitory for the requirement of engineering technique criterion. The compounded result is more economical and reasonable for actual project.更多还原
