摘　　要：土工合成材料加筋土技术是岩土工程中新发展起来的一个分支,该材料的设计原理和方法大多以岩土力学为基础。基于APDL语言编制的程序对加筋地基进行了非线性静力分析,采用ANSYS软件建立加筋地基的计算模型,并提取计算结果,结合现场载荷试验及室内三轴试验的结果绘制出相应于各级荷载下不同加筋层数下加筋复合地基的沉降和不同地基形式下的下卧软土层顶面的土压力分布图形。并对其进行了分析,深入了解了土工合成材料的加筋机理,为今后工程设计提供参考。As a new branch, geosynthetic reinforced soil technology is developed in geotechnical engineering field, the design principle and methods are mostly based on Rock and Soil Mechanics. In this paper, a reinforced foundation is analyzed with a nonlinear static analysis by a APDL language. The model of reinforced foundation is built by the software-ANSYS. According to the ANSYS results, Combined with the site loading test and the results of triaxial tests in laboratory, the settlement curve of different layers of reinforced composite foundation under corresponding loads and the soil pressure distribution graph on top of soft soil under different forms of ground are drawn. By analysis, the reinforcement mechanism of geosynthetics is understood deeply. It will provide a reference for future project design.
