摘要: 针对目前考虑位移的土压力计算方法都是建立在挡土结构侧向位移已知的基础上来计算土压力的,不适用于侧向位移未知的实际工程中。在充分考虑土与加固护岸板桩的相互作用的基 础上,建立了一种基于矩阵位移法和加固护岸板桩土压力计算模型的土压力计算方法。结合现场测试数据,在靠岸侧,土压力计算值和实测值分布规律较一致,两者之间的相对误差较小,最 大值仅为8.2%;在临水侧,土压力计算值和实测值分布规律较一致,除桩端处,两者的相对误差较小,最大值仅为3.2%,在一定程度上验证了考虑位移的加固护岸板桩桩侧土压力计算方法是 合理、可行的。

Abstract: Currently,the earth pressure calculation methods considering displacement are based on the known lateral displacement of retaining earth structure and are not suitable for the unknown displacement cases in reality.Therefore,on the basis of fully considering the interaction between soil and reinforcing revetment sheet piles,an earth pressure calculation method was established, which was based on matrix displacement method and earth pressure model of sheet pile for reinforcing revetment.Combined with the field test data,the calculated values of earth press agree with the measured values at bank side,the relative error between the two is small and the maximum value is only 8.2%.On the water side,the distribution rule of the calculated values of earth press and the measured values is almost the same.Except for the ends of piles,the relative error between the two is small and the maximum value is only 3.2%.To a certain extent,it is proved that the calculation method of soil pressure on the side of the reinforced bank sheet pile with the consideration of displacement is reasonable and feasible.
