边坡工程地质特性及稳定性评价——以石阡县环五方国际路网工程龙凤路为例

Engineering Geological Characteristics and Stability Evaluation of Slope——Taking Longfeng Road, a Five-way International Road Network Project in Shiqian County as an Example

文中概述了石阡县环五方国际路网工程龙凤路边坡工程地质特性,提出了场区边坡的岩土体力学参数,进而开展了边坡稳定性评价,并提出了该边坡的治理措施。结果表明:该边坡为土质边坡和岩土混合边坡,边坡岩质部分主要为强风化,土质部分为粉质粘土,根据折线滑动法,该边坡可能失稳。

Firstly, this paper summarizes the engineering geological characteristics of Longfeng road slope of Huanwufang international road network project in Shiqian Country, then puts forward the rock and soil mechanical parameters of the site slope. Then, the slope stability evaluation is carried out. Finally, the treatment measures of the slope are put forward. The results show that the slope is a soil slope and a rock soil mixed slope. The rock part of the slope is mainly strongly weathered and the soil part is silty clay. According to the broken line sliding method, the slope may be unstable.
