基坑单支撑拱形围护结构性状分析

Behavior analysis of single strut arched retaining structure in foundation pits

摘要: 针对单支撑拱形围护结构的性状作了较系统的分析 ,考虑了拱脚桩变形、插入深度、坑底土质、拱形状、支撑位置、支撑刚度、拱壁刚度和土压力平面分布形式等因素对单支撑拱形围护结构性状的影响。详细地分析了各因素对单支撑拱形围护结构性状的影响规律 ,这些规律对单支撑拱形围护结构的设计与应用具有重要的参考价值。

Abstract: The behavior of single strut arched retaining structure is analyzed. The influence factors include the deformation of arch foot pile, the embedded depth, the characteristics of soil under the bottom of excavation, the shape of arch, the position and the stiffness of strut, the stiffness of buttress and the distribution of soil pressure. The influences of these factors, which are important to guide the design and application of single strut arched retaining structure, are described in detail in this paper.
