公路工程地质灾害的发生往往与公路沿线及其周边的复杂的地质环境条件密切相关。本文主要以S301线托克逊-乌拉斯台段公路崩塌灾害为研究对象,对区内崩塌灾害的发育特征、危险性现状和预测进行了评估。研究结果表明:该公路沿线主要发育崩塌、泥石流、潜在地面塌陷,而滑坡、地面沉降和地裂缝等地质灾害不发育;现状评估均为危害程度中等和危险性中等的灾害点;预测评估工程建设引发或加剧崩塌灾害的危险性中等,可能遭受崩塌灾害的危险性中等。
The occurrence of highway engineering geological disasters is often closely related to the complicated geological environment along the highway and its surroundings. In this paper, the collapse of the Toxon-Uras stage highway in S301 is mainly studied, and the development characteristics, risk status and prediction of the collapse hazard in the area are evaluated. The results show that the main collapses along the highway, debris flow, potential ground collapse, and landslides, land subsidence and ground fissures and other geological disasters are not developed; the status quo assessment are moderate hazard and moderate disaster point; prediction and evaluation of project construction The risk of triggering or exacerbating a collapse hazard is moderate and the risk of being able to suffer a collapse hazard is moderate.
