| 摘 要： | 岗曲河一级水电站调压井边坡外缘岩层较薄,风化严重。针对这种现象,采用ANSYS软件建立岗曲河水电站调压井山体地表、岩层模型,并通过程序将其转化为FLAC3D数值计算模型,利用FLAC3D软件对调压井进行开挖支护模拟。通过分析调压井衬砌结构及围岩在施工期和运行期的变形特性,评价现有支护措施对调压井在施工期及运行期的稳定性。模拟结果表明,利用FLAC3D对调压井支护措施进行模拟,能很好地反映工程实际问题,为调压井工程设计和施工提供参考和指导作用。

| Abstract: | We establish the model of terrane and surge chamber by ANSYS for Gangquhe-1 Hydropower Station,which will be translated into FLAC3D numerical model,so as to simulate the excavation and support of surge chamber.Based on calculation of two construction process schemes,we evaluate stability of the existing support measures by analyzing the characteristics of horizontal and vertical displacement and stress-strain of reinforced concrete lining structure and surrounding rock during construction and operation resp... |
