土工格栅在路基浅层处理中的应用及技术要求

该文以软土地区路基浅层处理结构为研究对象,采用有限元法,对其中土工格栅加固软土地基进行了定量的分析,并对土工格栅本身在施工过程中和使用状态的受力进行了分析,得到了土工格栅能有效地加固软土地基,并对地基的不均匀沉降具有较高的适应性的结论,并且认为在工程设计中,一定要考虑施工过程和使用状态对土工格栅本身受力的要求,采用合适的土工格栅。该文对土工格栅加固软土地基的工程设计具有一定的参考意义。

Application and Technical Requirements of Geogrid in Shallow Treatment of Roadbed

Using the shallow treatment structure of roadbed in soft soil area as the research object,this paper adopts the finite element method to carry out the quantitative analysis of the soft subgrade reinforced by geogrid,and analyzes its stress condition of geogrid in the construction process and the using state.After that,this paper gets a conclusion that the geogrid can reinforce the soft soil subgrade efficiently and has the higher applicability to the asymmetry settlement of subgrade.The paper considers that it must be to take into account the requirement of construction process and using state to the stress condition of geogrid in the engineering design,and the suitable geogrid is used.This paper has some referring significance in the engineering design of using the geogrid to reinforce the soft subgrade.
