摘要

    摘要
  • 摘要: 为研究白鹤滩水电站左岸边坡岩石微破裂损伤状态下的宏观变形,基于现场微震监测数据以及宏观变形资料,运用震源半径表征岩石破裂尺度,采用考虑岩石破裂尺度的损伤本构关系,通过将岩石微破裂信息导入左岸边坡准三维数值模型,再现开挖工况左岸坝肩岩体卸荷变形过程,建立微震损伤与边坡宏观变形的定量联系。反馈分析结果表明：边坡岩体开挖工况下考虑微震损伤模型较未考虑微震损伤变形特征更接近于实际位移测值。考虑微震损伤效应的反馈分析方法作为一种初步的探索性工作,可为高陡边坡稳定性研究提供新思路。
    Abstract: In order to study the macroscopic deformation of the slope at the left bank of Baihetan Hydropower Station in the micro-fracture damage state, based on the micro-seismic monitoring and field deformation data, the source radius was used to characterize the rock fracture scale, and the constitutive relation considering the scale of rock fracture was used to introduce the fracture information into the slope at the left bank. A three-dimensional numerical model was used to reproduce the unloading deformation process of the rock mass of the abutment at the left bank during excavation, and to establish a quantitative connection between microseismic damage and field deformation of the slope. The feedback analysis shows that the microseismic damage model is more similar to the actual displacement measurement under the excavation conditions. The proposed feedback analysis method considering microseismic damage is a preliminary exploratory work and can provide new ideas for the researches on the stability of high and steep slopes.
