针对扶壁式挡土墙跨过地坑的特殊实际情况,基于对设置卸荷板的扶壁式挡土墙的受力原理的准确分析,采用改进过的扶壁式挡土墙,利用卸荷板有效的减小了挡土墙的土压力,挡土墙截面也相应减小,同时利用卸荷板上的覆土调整了挡土墙倾覆力矩,增大了滑移稳定性和倾覆稳定性,并通过植筋方式把原有地坑作为挡土墙的巨大底板,形成一种特殊的挡土墙结构,安全经济合理。
Aiming at the special actual situation that the buttress retaining wall crosses the pit, based on the accurate analysis of the principle of supporting force of the buttress retaining wall with the unloading plate, the improved buttressed retaining wall is adopted, The load plate effectively reduces the earth pressure on the retaining wall and the section of the retaining wall is correspondingly reduced. At the same time, the covering moment on the unloading plate adjusts the overturning moment of the retaining wall, increasing the sliding stability and overturning stability , And through the anchorage way to the original pit as a huge wall of the retaining wall, forming a special retaining wall structure, safe, economical and reasonable.
