| 摘 要： | 借助MARC软件,系统分析了桩周土体c、值及土体模量E值对大直径空心桩承载力的影响,分析表明E值是影响 大直径桩承载力的主要因素。文章进一步分析了桩端土体模量E对Se值(桩端沉降与桩顶沉降之比)及对桩身轴力曲线的影 响。通过与实测结果比较,证明所建模型合理。

| Abstract: | Using the MARC program, the authors analyze effects of soil parameters, such as cohesion, frictional coefficient, and elastic modulus, on the bearing performance of a large diameter hollow pile. The result shows that the elastic modulus is a controlling factor. The paper also evaluates the influence of the underlying soil,s modulus on the S e (the ratio of pile end settlement to pile top settlement) and the axial stresses. A close matching between the emulation results with the actual test data assures that the model is appropriate for analysis. |
