| 摘 要： | 云南昭通-待补高速公路（11合同K314＋550～K314＋700）红石岩段边坡加固中,因地质特殊,边坡高陡,在处治中采用预应力锚杆、抗滑锚杆桩、格构护坡、高压注浆等的混合式锚固结构.运用G-slope软件对加固前和加固后的路堑边坡的稳定性进行模拟和分析,分析结果表明：采用文中的加固方法,加固后的坡体稳定性较好,各种加固结构组成了一个有机整体,从而使坡体的稳定性得到了有效的控制.

| Abstract: | In the reinforcement of the side slope of Hongshiyan Sector in Yunnan Zhaotong-Daibu freeway (11 contract K314 + 550- K314 + 700), a composite anchor structure of prestressing anchor rod, anti-slippery anchor stake and high-pressure pouring-slurry is adopted as a result of its special geology and the steep side-slope. The stability of the cutting side-slope before and after the reinforcement is stimulated and analyzed with G-slope software. The result shows a better stability with the method mentioned in the paper, as various reinforcing structures forms an organic integration that effectively controls the stability of the slope. |
