摘　　要：加筋垫层的作用机理与承载性能的研究远远落后于工程实践,采用弹塑性有限元分析方法,分析了条形基础下软土地基在不排水条件下土工织物加筋垫层对地基承载力的影响。结果表明,对于土工织物存在一个最佳层数、最佳间距和最佳长度使得地基极限承载力最大。The research on the function mechanism and loading performances of the reinforced bar cushion is far beyond the project practices. With the elastic and plastic finite element analysis method, the paper analyzed the geotextile and reinforced bar cushion affected to the loading force of the ground base under the no water drainage in the soft soil base under the strip foundation. The results showed that the geotextile with a optimized layer number, optimized spacing and optimized length could make the ultimate loading force of the ground base to be in max.
