| 摘 要： | 在考虑均质黏土和均质砂土两种特殊地基情况下,运用三维有限元程序MSC.MARC,分析竖向荷载作用下桩基的水平反应.分析结果表明,竖向荷载对桩基的水平承载力有显著影响,在砂土中使桩基水平承载力显著提高,在黏土中则使其稍微减小.

| Abstract: | A three-dimensional finite-element program, MSC.MARC, was used to analyze the horizontal response of the pile under the action of vertical loads, and two specific foundation circumstances, homogeneous clay and homogeneous sand, were considered. The results of analyses showed that vertical loads can significantly increase the horizontal bearing capacity of the piles in sandy soils and marginally decrease the capacity in clavev soils. |
