As a whole , the research work of this dissertation can be summarized follows : 1 . in accordance with my design patent , namely , reinforced earth retaining wall of r c net , and based on the analysis of the work mechanism , failure pattern , bearing capacity and stability of the reinforced earth , a new concept is expounded , namely , the reinforced earth wall which is thought of as a compound structure increase not only c but also ~ in comparison with non - reinforced earth . some bearing capacity formula are first introduced under the circumstances that the reinforced earth wall fails because of the breakage of material or inadequate cohesion between reinforcements and soil 归纳起来，具体的研究和所获得的一些重要成果如下： 1 、结合本人的设计专利? “钢筋混凝土网格式加筋挡墙”及工程实践，在对加筋土的加筋机理、破坏模式、承载力和稳定性等方面进行深入分析的基础上，提出了一个新概念，即经过加筋后的土体作为复合结构与原土体相比，不仅提高了内聚力，而且也提高内摩擦角；并在此前提下首次导出拉力破坏和粘着破坏两种情形下的承载力公式，然后进行了稳定性分析。
