浙西南山区填方边坡加固措施及稳定性分析
Reinforcement Measures and Stability Analysis of Filling Slope in the Mountain Area of Southwest Zhejiang
摘要
Abstract
Taking the filling slope area in the mountainous area of southwest Zhejiang Province as research object,the mechanical properties of cement soil are studied through indoor experiments,and the influences of the changes of structural parameters of mixing piles on slope reinforcement and the stability of slope after reinforced by mixing piles are analyzed by strength reduction method and limit equilibrium method in finite difference software.The results indicate that,(a)the cement can improve the strength of soil,but the effect is limited;(b)increasing confining pressure gradually transforms the brittle failure of cement soil into plastic failure;(c)changing the horizontal distribution of piles has no significant effect on improving slope stability;(d)changing the position of pile reinforcement has a significant impact on the stability of slope,and selecting an appropriate reinforcement position is the key to strengthen the slope.关键词
