双平面滑动破坏模式下的陡倾顺层岩质路堑边坡稳定性研究

岩质边坡稳定性主要受其结构面控制。以恩施至来凤高速公路工程中宜恩县芭蕉乡黄泥塘村境内的一段整体式路堑边坡为例，为克服传统有限元方法计算岩质边坡稳定性的缺陷，先对岩质边坡双平面滑动破坏模式进行理论分析，最后通过工程实例验证离散元法计算岩质边坡稳定性的适用性。

Research on the Stability of Consequent Bedding Rock Cutting Slope with Steep Dip-angle under Double Plane Sliding Failure Mode

The stability of rock slope is mainly controlled by its structural plane. Taking a section of integral cutting slope in Huangnitang Village, Bajiao Town, Yi’en County of Enshi—Laifeng Expressway as an example, firstly, the double plane sliding failure mode of rock slope is theoretically analyzed in this paper in order to overcome some defects of traditional finite element method calculating the stability of rock slope, finally, one engineering example is brought in to verify the applicability of discrete element method calculating rock slope stability.
