摘要:
加筋承受拉力后,主要通过2个途径来改善土体的力学性能:(a)减少本该由土体承受的剪力; (b)通过增加剪切面上的正应力提高局部土体的抗剪强度.本文用准粘聚力概念(Pseudo cohesion concept),推导了土工合成材料加筋路堤的圆弧滑动稳定性验算改进公式,并指出,当土工合成材料加筋层的填土为砂性土时,宜采用改进公式计算结构稳定系数.
Abstract:
Reinforcement added in embankments achieves mechanical improvement by supporting tensile force which acts (a) to reduce the shear force that has to be carried by the soil, and (b) to enhance the available shearing resistance in the soil, by increasing the normal stress acting on potential shear surface. According to these actions and the pseudo cohesion concept, the paper presents an improved formula instead of the conventional one to analyze the stability of slip circle in reinforced embankments and the advisable occasions which to apply the improved formula. 
