摘要:
为研究有限宽度下衡重式挡土墙墙后主动土压力规律和支护有效性，以开挖高边坡支护工程为对象，结合实际情况和理论公式进行衡重式挡土墙抗滑抗倾覆验算，选取2个断面共计20个土压力盒和4个建筑物沉降监测仪的数据进行研究。结果表明：衡重式挡土墙外侧土压力高于内侧土压力，呈向外倾斜的趋势，在衡重台高度处存在骤减现象；运营期土压力变化幅度减缓，对后侧建筑物沉降影响减小。
Abstract:
In order to study the law of active soil pressure and the effectiveness of support behind a balanced gravity retaining wall with limited width，this paper conducts a case study on the slope support work of excavation. Based on the actual situation and theoretical formulas，the anti-sliding and anti-overturning checking calculation of the balanced gravity retaining wall was carried out. The data of 20 soil pressure cells and 4 building settlement monitors from two sections were selected for analysis. The results show that the soil pressure on the outer side of the balanced gravity retaining wall is higher than that on the inner side，showing an outward inclination trend，and there is a sudden decrease at the height of the gravity platform. During the operation period，the change in soil pressure slows down，reducing the impact on the settlement of the buildings behind the wall.
