| 摘 要： | 对于柔性支护挡土墙,在计算土压力时,宜考虑土压力作用点位置对其计算数值的影响。提出一个建立在Bishop法基础上的简化法。当土压力作用点位置为下三分点时,计算成果可无一例外地收敛到经典的库仑理论值。作用点位置为墙高中点时,经算例分析,主动土压力相应下三分点时的数值增加了15%左右。

| Abstract: | When calculating the earth pressure for flexible retaining walls,the influence of application point of the earth pressure on numerical calculation should be taken into account.A simplified method of calculating the active earth pressure for the flexible retaining walls is proposed.When the application point of earth pressure is located at the one-third point of the wall,the calculated results exactly converge on the classical Coulomb theoretical solutions.When the application point is at the middle point of... |
