| 摘 要： | 基于疏排桩间抛物线土拱轴线和平面主动滑裂面的假设,建立了疏排桩-土钉墙组合支护结构的荷载分担和整体稳定计算模型,得到了相应的计算公式.参数分析表明:疏排桩-土钉墙组合支护结构的支护特性介于疏排桩与土钉墙的支护特性之间,且随参数变化表现为以疏排桩或土钉墙的支护特性为主导.建议在应用当中,根据工程条件,选择其主导特性进行设...

| Abstract: | Based on the hypothesis of parabola soil arch axes and active slip plane,the computational model of load transfer behavior and integral stability for composite structure with scattered piles and soil nailing(PSN) is established and calculat on formulas are obtained.The parametric studies show that the retaining characteristic of PSN is that between scattered piles and soil nailing and the dominant characteristic of PSN depends on its parameters.It is suggested that the dominant characteristic of PSN should ... |
