层状岩质边坡稳定性评价——以连云港市云台山山岭东端开挖边坡为例

Stability Evaluation of Layered Rock Slope——Taking the Excavated Slope at the East End of Yuntai Mountain in Lianyungang City as an Example

文中论述了连云港市云台山山岭东端开挖边坡的工程地质条件,分析了该边坡可能的破坏模式,并评价了该开挖边坡的稳定性。结果表明,该边坡可能发生层面滑动或楔体破坏,边坡目前均已处于极限平衡状态,在遇到降雨、地震、爆破等特殊工况下,边坡会处于不稳定的状态。

Firstly, the engineering geological conditions of the excavated slope at the east end of Yuntai Mountain in Lianyungang City are summarized. Afterwards, the possible failure mode of the slope is analyzed. Finally, the stability of the excavated slope is evaluated. The results show that the slope may be subject to layer sliding or wedge failure. At present, the slope is in the limit equilibrium state. Under special conditions, such as rainfall, earthquake and blasting, the slope will be in an unstable state.
