四川通江县马1井井场公路地质灾害危险性预测评估及防治

The Geological Disasters Assessment and Prediction Control of Ma 1 Well Field Road in Tongjiang,Sichuan

拟建的马1井场公路位于通江县北部四川盆地与米仓山构造带的转换部位,工程规模较大,地质条件较复杂。在公路建设中,可能诱发或加剧的地质灾害主要表现为深路堑开挖形成的高陡边坡失稳崩塌或滑坡,高填方软弱地基的不均匀沉降导致路基变形失稳、岩石风化碎落等地质灾害。本文在公路工程区现状评估和预测评估结果的基础上,根据不同的灾种和危险性提出相应的措施防治。

Ma 1 well field road is located in the northern part of Sichuan Basin Tongjiang County and Micangshan tectonic belt conversion parts with engineering larger and more complicated geological conditions. In road construction,may trigger or exacerbate the geological disaster is mainly expressed in the formation of deep excavation of high and steep slope instability or collapse landslides,high fill soft ground resulted in differential settlement of subgrade deformation instability,rock weathering and other geological disasters. In this paper,the status in the road engineering district assessment and prediction based on the results of the assessment,based on different kinds of disaster and risk prevention and control measures put forward.
