悬臂式挡土墙结构形式研究

Study of structure form of cantilever type retaining wall

介绍了挡土墙的结构形式和几种土压力的计算方法,通过工程实例计算研究了悬臂式挡土墙,墙身底宽对抗滑、抗倾、基底压力的影响。计算结果表明,在墙身高度一定时,随着墙身底宽的增大,抗滑系数缓慢增大,抗倾系数逐渐增大,基底压力逐渐增大,大小应力比值也在增大。

The paper introduces the structure form of retaining wall and calculation methods of several earth pressures,studies the influences of cantilever type retaining wall bottom width on anti—slide,anti—overturning and foundation pressure by using the engineering example.When the height of the retaining wall is Constance,the more the wall bottom width is,the larger the coefficient of anti—slide and anti—overturning are and the larger the foundation pressure and the ratio of maximum and minimum stress are.
