根据河南省洛 (阳 )三 (门峡 )高速公路 K97+ 90 0～ K98+ 5 0 0路段高陡风化安山岩路堑边坡失稳的具体情况 ,设计采用了预应力锚杆、抗滑锚杆桩、挡土墙、喷射混凝土及中高压注浆的复合加固方式。根据各种加固结构的不同属性 ,采用数值计算的方法 ,对加固后路堑边坡的整体稳定性以及加固结构的承载性能进行了模拟分析。分析结果表明 ,加固后的坡体稳定性较好 ,设计中所施加的 15 0 k N的预应力值也比较合理 ,同时各种加固结构组成了一个有机整体 ,从而使坡体的整体稳定性得到了有效控制。
According to the specific conditions of the instability of cut slope of high-steep andesite in K97 + 90 0 ~ K98 + 500 section of Luoyang-Yangshou Sanmenmen-Mukou Expressway in Henan Province, prestressed anchors, anti-skid bolting piles, Retaining wall, shotcrete and medium and high pressure grouting compound reinforcement method. According to the different properties of various reinforced structures, numerical calculation method is used to simulate the overall stability of the reinforced cutting slope and the bearing capacity of the reinforced structure. The analysis results show that the stability of the stabilized slope is good, and the prestressed value of 15 0 kN applied in the design is also reasonable. At the same time, the various reinforced structures form an organic whole, so that the overall stability of the slope Has been effectively controlled.
