本文在锚定板式挡土墙和悬臂式挡土墙的基础上,提出了一种路基新型支挡构造物—-路基悬锚式挡土墙,并依托延安经志丹至吴起高速公路修筑悬锚式挡土墙实体工程,对其混凝土应变变化进行分析研究。通过对实体工程混凝土计应变实测数据的分析,可以得出在墙体外侧布设的混凝土计,无论是横向还是竖向其所测数据均为负值,且同一断面上混凝土应变沿墙高方向由下向上逐渐增加,而同一高度的混凝土应变由边跨(与伸缩缝相邻)向中跨部位逐渐减小。牛腿处布设的混凝土计所测数据均为正值,且由边跨向中跨近似于线性递减。
Based on the anchoring plate retaining wall and cantilever retaining wall, this paper presents a new type of subgrade retaining structure-subgrade retaining anchorage retaining wall, and relies on Yan’an Jingzhi Dan to Wuqi Expressway Anchor retaining wall solid engineering, analysis of the concrete strain changes. Through the analysis of measured data of concrete engineering concrete strain gauge, it can be concluded that the concrete meter laid on the outside of the wall has negative values both in horizontal direction and vertical direction, and the concrete strain in the same section is along the height direction of the wall While the concrete strain at the same height gradually decreases from the side span (adjacent to the expansion joints) to the midspan. The measured data of the concrete meter laid on the leg of the cow is positive, and it is linearly decreasing from the side span to the middle span.
