| 摘 要： | 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,导出作用于双排桩桩侧的坡体土压力分布；然后针对双排抗滑桩桩间土体有限边界特点,通过对桩间土不同区域分别采用薄层单元法对土压力的分布模式进行求解,导得桩间土作用于双排抗滑桩桩侧土压力分布,由此得出...

| Abstract: | The most disadvantaged load bearing condition of double-row anti-slide piles structure was analyzed.First,considering the longitudinal soil arching mechanism between piles,and making use of geometrical characteristic of parabolic soil arching axis as well as equilibrium and stress states of arch springing,the distribution of slope soil pressure against double-row piles was derived.Second,according to the characteristics of limited boundary between double-row anti-slide piles,by using thin-layer element meth... |
