摘要
以重庆铁路枢纽东环线某生态护坡技术示范工程为例,利用Midas GTS/NX有限元软件建立了灌草护坡方案、矮墙—灌草护坡方案、格构锚杆—灌草护坡方案的数值模型并对3种不同护坡方案进行了稳定性分析。结果表明:灌草护坡方案使边坡土体的潜在滑动区域变深,塑性区域变小;格构锚杆—灌草联合护坡时,边坡的安全系数最大;矮墙—灌草联合护坡的安全系数比灌草护坡的安全系数略大。
Taking a demonstration project of ecological slope protection technology on the East Ring Line of Chongqing Railway Hub as an example,the Midas GTS/NX finite element software is used to establish the numerical values of grass-filling slope protection scheme,low wall-grass-filling slope protection scheme,lattice anchor-grass-filling slope protection scheme.The model and stability analysis of three different slope protection schemes are carried out.The results show that:the shrub-grass slope protection scheme makes the potential sliding area of the slope soil deeper and the plastic area smaller;the safety factor of the slope is the largest when the lattice anchor-shrub and grass combined slope protection;the safety factor of the low wall-shrub and grass combined slope protection is not much different from that of the shrub and grass slope protection.
