考虑土拱效应双排抗滑桩桩侧土压力计算
he calculation and application of double-row anti-slide piles soil pressure considering soil arching effect
分析了双排抗滑桩结构承载的最不利状态。首先考虑纵向桩间土拱成拱机理，利用土拱抛物线拱轴线的几何特征及拱脚处的力平衡及应力状态，导出了作用于双排桩桩侧的坡体土压力分布；试验数据对比表明，该方法计算结果与实测数据较为接近，可供双排桩设计参考。
he most disadvantaged condition of double-row anti-slide piles structure bearing limitation is analyzed. Firstly, considering the longitudinal arch piled soil arching mechanism, and making use of soil arch geometry axis parabolic arch and arching at the static equilibrium, and then educing the slope soil pressure distribution of the double piled side. Calculation example shows that the method has very high precision and can be as a reference for double piles design.
