以景德镇某地区二元结构基坑工程为研究对象,对采用锚杆和抗滑桩支护条件下采用整体开挖、分步开挖、整体跳挖、分步跳挖等四种开挖方式的基坑的稳定性进行定量分析。借助数值模拟软件建立支护模型,在边坡不同位置设置观测点,通过对比不同工况下模拟结果,总结出抗滑桩对于维持二元结构边坡稳定性具有可靠作用,采用分步跳挖的开挖方式更加有利于二元结构基坑边坡的稳定性。
Taking the construction of the two-dimensional structure foundation pit in a certain area of Jingdezhen as the research object, the excavation methods of integral excavation, step-by-step excavation, integral excavation, step-by-step excavation and so on under the conditions of bolt and anti- The stability of the foundation pit for quantitative analysis. The numerical simulation software is used to establish the support model and the observation points are set at different positions of the slope. By comparing the simulation results under different working conditions, it is concluded that the anti-slide piles have a reliable effect on maintaining the stability of the binary structure slope. The excavation method is more conducive to the stability of the pit slope of the dual structure.
