摘要

被动阻力的知识是极其重要的，它是设计土工结构所需的基本数据，如挡土墙向回填体移动、基础、锚等。本文尝试用拟静力法推导出c-F填料挡土墙地震被动抗力演化公式。考虑到一个平面破裂面，该公式是这样发展的，以便产生一个单一的临界楔面。在内摩擦角、壁面摩擦角、黏聚力、黏附力、堆填量、回填材料单位重量、高度、地震系数等参数大范围变化的情况下，研究了地震被动土压力系数的变化规律。

Formulation of Seismic Passive Resistance of Retaining Wall Backfilled with c-F Soil

Knowledge of passive resistance is extremely important and it is the basic data required for the design of geotechnical structures like the retaining wall moving towards the backfill, the foundations, the anchors etc. An attempt is made to develop a formulation for the evolution of seismic passive resistance of a retaining wall supporting c-F backfill using pseudo-static method. Considering a planar rupture surface, the formulation is developed in such a way so that a single critical wedge surface is generated. The variation of seismic passive earth pressure coefficient are studied for wide range of variation of parameters like angle of internal friction, angle of wall friction, cohesion, adhesion, surcharge, unit weight of the backfill material, height and seismic coefficients.
