摘要
在挡土墙中加设卸荷板已经成为提高挡墙安全性、优化挡墙设计、减小工程量的重要手段。该文针对卸荷板式扶壁挡土墙的主动土压力进行分析,推出卸荷板式扶壁挡土墙主动土压力的计算公式,再运用公式分析其卸荷效应,最后通过实际工程进行验证,以期对类似的工程有借鉴意义。
Setting unloading-board in the design of buttressed retaining wall has become an important means to improve the safety of retaining wall, to optimize the design and reduce quantities.The active earth pressure of buttressed retaining wall with unloading-board has been analyzed, and a formula has been derived for calculating active earth pressure of it, then the formula has been used to analyze the unloading effect.Finally, this method, which is verified by the practical engineering, has been expected to provide reference for the similar engineering.
