西南某水电站拱肩槽高边坡稳定性的二维有限元分析

FEM ANALYSIS OF THE STABILITY OF THE SPANDREL GROOVE HIGH SLOPE OF A HYDROELECTRIC POWER STATION IN SOUTHWEST CHINA

采用数值模拟方法研究和论证我国西南某水电站拱肩槽高边坡的稳定性。重点对左岸拱肩槽边坡在自然状态下和施工开挖过程中以及开挖后的应力、应变场特征和演化规律进行了二维有限元分析 ,并据此对边坡的稳定性进行分析与评价 ,为设计和施工提供了科学依据。

The paper adopts the numerical simulation method to discuss and analyze the stability of the spandrel groove high slope of a hydroelectric power station in the southwest China. Especially,it pays much more attention to the left spandrel groove high slope, whose features and the evolvement rules of the strain-stress are analyzed according to the FEM analysis in the natural state, during the process of the excavation and after the excavation.Based on these,the paper analyzes and evaluates the stability and provides scientific evidences for the design and the construction.
