摘要
针对设有压顶梁和一道内支撑体系的支护结构 ,提出准空间计算模型 ,采用固定支撑法假定 ,推导了考虑压顶梁、支撑围檩等圈梁影响的支护桩内力、变形的解析形式 ,并通过对一实例的计算 。
A semi spatial model to analyze the behaviors of the retaining piles in deep excavation is presented. Based on fixed support assumption at the bottom of the piles, analytical formula for calculating the bending moments and deformations of the piles is gotten. It can account for the top beam and strut wale effects. The spatial effects and influence of the wale is shown by a case study.
