地下连续墙或防渗墙施工中槽孔的开挖是极其重要的分项工程,泥浆护壁条件下槽壁的稳定性影响因素很多.应用ABAQUS有限元软件,考虑泥浆的渗透,模拟计算不同密度的泥浆以及泥浆分层后槽壁的位移,对槽壁的稳定性进行分析.经对槽壁位移值的分析得到泥浆密度增大槽壁的位移随之减小以及减小的幅度,随着泥浆的沉淀,槽壁位移增大.研究可为槽孔施工时的泥浆控制提供定量参数依据.
The excavation of the slot in underground continuous wall or cutoff wall construction is an extremely important sub-project, and the stability of the slot wall under slurry retaining wall condition is affected by many factors.Using ABAQUS finite element software, considering the infiltration of mud and simulating the different density Of the mud and the mud layer after the displacement of the displacement of the wall to analyze the stability of the tank wall displacement value through the analysis of the tank wall density displacement increased as the tank wall displacement decreases and the magnitude of the decrease with the The sedimentation of mud and the displacement of the groove wall increase.The research can provide quantitative parameters for the mud control during the construction of the slot.
