| 摘 要： | 为有效地减少主动土压力,常常在挡土墙后设置减压平台。减压平台限制了墙后滑动面,此时滑动土体不再是一个楔体,无法采用朗肯理论、库仑理论计算土压力。减压平台的位置不同、长度不同,都会影响土压力的大小和分布。建立长、短减压平台的判别模式,探讨不同种类的减压平台土压力计算方法,提出建议和措施。

| Abstract: | Inorder to reduce the active earth pressure effectively,the relieving platform is commonly installed behind the retaining wall.The relieving platform limits the sliding plane,and the sliding mass at this time is no longer a voussoir,so,Rankine theory and Coulomb theory can't be applied to calculate the earth pressure.The earth pressure and distribution depend on the location and length of the relieving platform.Therefore,the proposal and measure establishing judgment mode for long and short relieving platform are raised to seek the calculation method for the different kind of platform. |
