摘要

摘要: 立柱桩隆起可能导致基坑内支撑系统失稳,严重时可能导致结构开裂甚至破坏,但是目前尚未有明确、系统的计算方法。基于对基坑卸荷应力与回弹变形的认识,针对不同的开挖工况,分析桩、土间由于回弹影响深度不同而出现的两种相互关系,计算分析了部分典型上部结构的刚度影响,提出了立柱桩隆起的简化计算方法。将计算结果与实测值进行对比验证,提出了部分修正参数,验证了该计算方法的可靠性。

Abstract: The heave of soldier piles in foundation pit may lead to system instability and structural cracking or failure. So far, there is no theoretical way for calculating the heaving soldier piles. Based on the unloading stress and rebound deformation of excavations, a simplified method for the heave of soldier piles is proposed considering two types of relations between the depth of the rebound effect under different excavation conditions. The influence of some typical upper structures on stiffness is analyzed. The calculated results are compared with the measured values. Some corrected parameter are proposed. The feasibility of the proposed method is validated.
