摘要:
依托高速公路加筋土柔性挡墙建设项目，对钢丝网加筋土挡墙进行现场监测分析，研究此种新型加筋挡墙结构形式在逐层填土过程中以及施工结束后，水平方向和竖直方向土压力的分布规律；借助数值分析软件FLAC，对双绞合六边形钢丝网加筋土挡墙进行了数值模拟. 研究表明，墙底处水平、竖直和45° 三个方向的土压力随着填土高度的增加而增大，施工完成后趋于稳定；各层筋材处竖向土压力随着填土高度的增加而增大，对于同一层筋材不同位置，竖向土压力分布不均；随着填土高度的增加，墙后水平土压力先增大后减小，呈单峰变化，数值模拟与实测值变化规律基本一致.
Abstract:
Based on a double twisted hexagonal wire mesh reinforced earth retaining wall built along an Expressway, we investigate the soil pressure in a cross section by field test and numerical simulation by FLAC, focusing on the horizontal and vertical earth pressures during and after wall construction. Results show that the earth pressures on the wall toe in 3 directions including horizontal, vertical, and 45° increase with the height of filling soil and gradually come to stability after wall construction, and the vertical earth pressures increase and the distribution for earth pressure at the same height is not uniform. The horizontal earth pressure on the back of the wall face increases fast at first but then decreases a little, appearing as a single peaked shape. The numerical simulation result coincides with the field test result.
