在水利工程中,悬臂式挡土墙是钢筋混凝土挡土墙的主要形式,组成部分包括立板和底板。因此,对悬臂式挡土墙主动土压力计算问题,就是施工设计中必须要考虑的问题。文章针对填土表面水平且无粘性的条件下,通过水平微元法推求悬臂式挡土墙后出现三角形滑动土楔时的主动土压力,得到主动土压力合力作用点高度以及主动土压力沿墙高分布的变化规律。
In water conservancy projects, cantilever retaining wall is the main form of reinforced concrete retaining wall, consisting of vertical plate and floor. Therefore, the calculation of active earth pressure on cantilever retaining wall is a problem that must be considered in the design of the structure. In this paper, aiming at the condition that the filling surface is horizontal and non-sticky, the active earth pressure at the triangular sliding earth wedge after the cantilever retaining wall is deduced by the horizontal-element method. The height of the active earth pressure acting point and the active earth pressure along the wall High distribution of the law of change.
