| 摘 要： | 抗滑桩的设计理念是采用非连续结构,利用土体自身强度形成的拱效应来达到支挡目的。土拱效应是安全经济地发挥抗滑桩等非连续支挡结构支护功能的重要前提。通过对非均布荷载作用下土拱的力学性质分析,根据轴向压应力与矢跨比的函数关系,利用摩尔-库仑强度准则推导了土拱承载力与土拱净跨度和桩宽度的关系。

| Abstract: | The concept of designing anti-slide pile is using discontinuous structure and the soil arching effect due to soil body strength to support the sliding force.Soil arching effect is an important precondition of adjacent pertaining or anti-sliding pile working safely and cost-efficiently.By means of the analysis of mechanical concepts of soil arching under the uniformly distributed load,based on the mechanical properties of soil arch,according to the function relation of the axial compressive stress and the ri... |
