| 摘 要： | 为了考虑填土凝聚力及其与挡土墙墙背接触面上粘着力计算粘性成层填土挡墙的土压力,假设滑裂面为平面,运用数学、力学手段,推得了粘性成层填土挡墙的主动土压力计算公式,编制了相应的计算程序,进行了算例分析.结果表明:考虑与不考虑滑裂面上的凝聚力c及墙背上的粘着力cw,计算结果差异较大,该差异随着c、cw的增大而增大;公式精度可靠,应用方便.

| Abstract: | To study the active earth pressure of retaining wall with multiple layers of cohesive soil,based on the hypothesis of sliding plane and methods of mathematics and mechanics,a formula is proposed considering the cohesion force on sliding surface and the adhesive force on interface of retaining wall.A program is designed for the formula.A calculation sample shows the diversity of calculating results with or without the consideration of the cohesion force c on sliding surface and the adhesive force cw on interface of retaining wall,and the diversity increases with the rising c and cw.The formula is reliable and easy to be applied to projects. |
