桩承土工合成材料复合地基的研究

Study on the Composite Ground with Pile-bearing Geosynthetics

介绍了桩承土工合成材料复合地基的作用机理 ,应用改进的太沙基原理 ,分析了土工复合材料复合层地基承载力的计算 ,并通过在连霍高速公路三门峡～灵宝段软基处理中应用的工程实例验证 ,桩承土工合成材料复合地基可加速软土地基固结 ,提高路基路堤稳定性 ,加快填筑速率 ,缩短工期。

The function mechanism of pile-bearing geosynthetics is introduced.The calculation of the bearing capacity of the composite ground is analyzed by the improved Terzaghi principle.Through the application of the method to the soft soil treatment of the expressway at the section from Sanmenxia to Linbao, it is shows that the composite ground with pile-bearing geosynthetics can accelerate the consolidation of the soft soil, can improve the stabilization of the roadbed and road bank,can accelerate the speed of filling and shorten the construction time.
