土工格栅加筋黏土抗剪强度三轴试验韩志型1,王宁1(1.四川省绵阳市西南科技大学土木工程与建筑学院)摘 要:通过土体三轴受压条件下的无侧向静止土压力系数和摩尔-库仑定理,将加筋黏土体在三轴受压条件下的总体抗剪强度分为加筋土体发生侧向变形前的强度和与土工格栅密切相关的土体发生侧向变形后的强度两部分进行研究.在不同含水量下加筋黏土的三轴试验及其所得相关数据分析的基础上,提出利用加筋土体发生侧向变形后的抗剪强度与极限抗剪强度的比值p2随加筋层数的变化情况作为评价加筋效果的重要指标.试验结果表明,当黏土在最优含水量状态下......
took both matric suction and intermediate principal stress into account and was suitable for any lateral pressure coefficient. Comparability analysis and parametric studies were carried out...-consolidation, the critical load with lateral pressure coefficient of 1 is higher; the intermediate principal stress effect should be fully considered and an appropriate lateral pressure coefficient......
