五强溪水电站船闸边坡的粘弹性位移反分析及变形预测

Visco-elastic back-analysis on displacements and prediction of deformation in the shiplock slope of Wuqiangxi hydroelectric power station

摘要: 位移反分析的提出,可望为边坡工程设计工程师提供一个确定有关地层力学参数和某些地应力分量的新方法。本文针对五强溪水电站左岸边坡岩层的特点,选择了HK模型,并从该边坡的实测位移出发,反演该边坡工程设计所需要的岩体力学参数。文中较详细地阐述了有关原理和可行的方法

Abstract: The back analysis on displacements may provide a new method for engineers responsible for the slope engineering design to choose mechanical parameters and some components of the initial stress. On the basis of characteristics of the strata of the slope in the left bank of Wuqiangxi hydroelectric power station, H K model is selected, and mechanical parameters required for the slope engineering design are back analyzed from measured displacements of the slope in this paper. Its principle and method are discussed in details.
