摘要
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。
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.
