摘　　要：土工合成材料在软土地基中应用较为广泛。对软土路堤解决方案进行了统计分析,介绍了软土地基加筋的基本规定,相应分析方法。在软土地基中,土工合成材料加筋层存在时,软土地基位移显著减小,其稳定性增强。有无筋材存在时,其承载力之比是影响基础性能的关键参数,且该承载力之比存在一个最佳值。Geosynthetics has been widely applied in the soft soil foundation.In this paper,the soft dirt road embankment solutions are analyzed.This paper introduces the basic provisions of reinforcement,and the corresponding analysis method.The results show that in the soft soil foundation,the presence of the geosynthetic materials reinforced layer decreased the soft shift significantly,and enhanced its stability.In case of the presence or the absence of the reinforced materials,the ratio of its bearing capacity is the key to the property of foundation parameters,and an optimum value exists in the ratio of its carrying capacity.
