摘要: 采用FLAC3D对桩锚支护结构变形的坑角效应及其影响因素进行模拟,对桩锚支护结构变形的空间分布进行了分析,得到桩锚支护结构变形坑角效应的影响范围,计算出桩锚支护结构变形坑角效应的影响系数,提出了一种考虑坑角效应的桩锚支护结构变形计算方法,并通过工程实例对此系数和计算方法进行了验证。

Abstract: The corner effect of a deep excavation supported by the soldier pile and ground anchor system as well as factors that impact the this effect are evaluated by the commercial finite difference analysis software FLAC3D. The spatial distribution of the deformation due to the excavation is evaluated and the influence of the corner effect can be quantified. The corner effect coefficient is therefore obtained and the deformation prediction method that considering the corner effect is proposed and verified by the excavation monitoring data.
