公路高边坡稳定性分析与加固措施研究

Analysis on Stability and Study on Reinforcement Measures of Highway High Slope

随着我国基础设施建设向偏远山区的不断推进,经常会遇到高填深挖边坡:在各种因素作用下,这种边坡很容易产生失稳问题,而土工格栅是改善其稳定性的最为有效的方法。通过系统阐述边坡稳定性的影响因索并分析土工格栅的加固理论,采用Midas GTS对工程实例建立数值分析模型,证明了土工格栅加固高填方边坡的有效性.

With the continuous advancement of the infrastructure construction to remote mountainous area in China,the high-filled and deep-excavated side slope is often encountered.Under various factors,this kind of side slope is prone to instability,and the geogrid is the most effective method to improve the stability of high slope.This paper systematically sets forth the influencing factors of slope stability and analyzes the reinforcement theory of geogrid.The numerical analysis model of engineering case is established by using Midas GTS to prove the effectiveness of the geogrid to reinforce the high-filled side slope.
