| 摘 要： | 采用弹塑性有限元计算方法,对堆积体滑坡中双排抗滑桩及其周围土体的受力及变形进行计算,对桩顶位移、桩身最大剪力、弯矩与滑体及滑床强度参数c,φ值的相互关系进行了参数敏感性分析。结果表明:双排抗滑桩的变形与受力,受滑体黏聚力的影响大,受其内摩擦角的影响小,而滑床的参数变化对双排桩的影响更小。

| Abstract: | By use of elasto-plastic finite element method, the force and deformation of double-row anti-slide piles in talus landslide and the soil mass surrounded were calculated, and then the sensitivity analysis was conducted in connection with the relations between the parameters of the pile top displacement, the maximum shearing force and bending moment of the pile body, the strength parameters c, φ values of the sliding mass and sliding bed.The results show that the cohesion of sliding mass has major influence on deformation and force on double-row anti-slide piles, and the internal friction angle thereof has minor influence;however, the parameters change of sliding bed has little influence on double-row piles. |
