【摘要】介绍了格栅的材料特性,对传统的计算土工织物处理软土地基承载力的计算方法的局限性进行了分析;利用有限元法编程,对格栅处理软土地基承载特性进行了研究;证明了格栅加层可以改善一定深度内地基内部的应力分布,从而提高软弱地基承载力的效应.更多还原

【Abstract】 Geogrid is a new kind of material with high strength. Because of its high strength and the special interaction between soil and geogrid, an entire soil-geogrid layer is founded within the soil. It modifies the distribution of stress in the base, and improves the bearing capacity of the soft base. A program is compiled, in which finite element method is used to verify the result.更多还原
