栈道基础埋深对现状悬臂式挡墙的影响研究

Research on the influence of foundation buried depth of plank road on existing cantilever retaining wall

栈道基础埋深较浅时,栈道荷载倾覆力矩的力臂过长,不利于现状悬臂式挡墙倾覆稳定;栈道基础埋深较深时,基础自重增加,基础底部应力扩散较小,不利于现状悬臂式挡墙地基承载力及沉降的均匀性;利用有限元软件Midas GTS NX,分析不同埋深基础时对现有挡墙的影响,得到对现状挡墙影响较小的基础埋深范围。在基础埋深优化的情况下,采取其他措施保障现状悬臂式挡墙的安全。

When the plank road foundation is shallower,the arm of the plank road load overturning moment is too long,which is not conducive to the overturning stability of the existing cantilever retaining wall;when the plank road foundation is deeper,the foundation weight increases,and the stress spread at the bottom of the foundation is small,which is not conducive Existing cantilever retaining wall foundation bearing capacity and uniformity of settlement;using the finite element software Midas GTS NX to analyze the influence of different buried depth foundations on the existing retaining wall,and obtain the foundation buried depth with less impact on the existing retaining wall Scope.In the case of the optimization of the buried depth of the foundation,other measures shall be taken to ensure the safety of the existing cantilever retaining wall.
