土工合成材料加筋垫层处理软基承载力探讨

Discussion about Bearing Capacity of Soft Ground Reinforced with Geosynthetics Reinforcement Cushion

介绍了土工合成材料加筋垫层对侧向变形的约束、隔离、减载、应力扩散等加固作用机理,并根据其作用机理和软基特性对改进的太沙基承载力公式进行了修正,提出了加筋垫层处理软基的承载力修正公式,通过工程实例分析认为,其具有较好的实用价值,对加筋垫层作用机理认识和设计计算有一定的参考价值.

Constraint function of lateral deformation, insulation, load lowering, stress diffusion of geosynthetics reinforcement cushion are introduced. According to its reinforcement mechanism and soft ground character,Terzaghi bearing capacity formula is improved. Corrected formula of bearing capacity of reinforcement cushion is obtained. Corrected formula is proved to be effective via analyzing and contrasting project example. The above is valuable to study of reinforcement mechanism and designing calculation of reinforcement cushion.
