以吉河高速公路乡宁西互通A匝道深挖路堑边坡诱发的滑坡为例,从互通设置情况、新收费站管理场区位置的选择、滑坡体的卸载支挡以及高压铁塔相邻侧已开挖边坡的加固等几方面入手,最终确定该滑坡影响范围的综合治理方案。实践证明该滑坡已处于稳定状态,达到滑坡处治目的。

Taking the landslide induced by deep cut slope of the interchange ramp-A of Xiangning West section in Jihe Highway as the example,this paper started with the setting of the interchange,the position selection of the new toll station management area,the unload support of the landslide,the reinforcement of excavated slope adjacent to the high-pressure tower and other aspects,the comprehensive treatment plan of the landslide range was determined.The practice proved that the landslide was in a stable state and the purpose of landslide treatment was achieved.
