3.Bearing capacity and displacement are two main problems in the application of geotechnical engineering.Based on a series of pull-out tests using three kinds of paper and a sort of window screening as geogrid,twenty-seven in limit and several in working-stress geogrid-reinforced slope model tests designed through orthogonal principle have been conducted to have obtained the relationship between the bearing capacity and four factors (i.e.reinforcement,angle of reinforced slope,the designed-length of reinforcement and the distance between layers of reinforcement).The law of slope lateral (horizontal)displacement versus to the height of slope vary with external-load was derived from the model test data,and the main factor affecting the lateral and vertical displacement of geogrid-reinforced slope was obtained through analysis.
承载力(强度)和变形是岩土工程应用领域的两大主要问题，本文以纸和窗纱布模拟加筋土边坡的土工格栅，在一系列拉拔试验的基础上，以正交设计理论分别安排27个极限应力状态和若干个工作应力状态加筋土边坡模型试验，并以模型试验获得的数据为依据，采用误差、极差及回归分析方法，探讨了加筋土边坡承载力与筋类、筋长、层间距、坡角4因素的相关关系，获得了在外荷载作用下加筋土边坡的侧向位移随坡高的变化规律(并进行了定性解释)和坡顶的竖向位移特性，并分析其主要控制因素。收藏指正
