基于几何测量法的裂隙岩体渗透性研究
PERMEABILITY STUDY OF FRACTURED ROCK MASS BASED ON GEOMETRY MEASURING METHOD
【摘要】 基于某坝址区左岸灌浆平硐裂隙实测结果,建立了裂隙岩体渗透系数张量计算方法,并开发了渗透系数张量计算软件。运用该软件对某坝址区左岸灌浆平硐中裂隙的渗透性进行了计算,计算结果得到了现场的验证,故该软件可以作为压水试验反演分析的补充,可为岩体渗透性分区及防渗帷幕的优化提供科学依据。
【Abstract】 The traditional and modern measurement methods of fractures are used to measure the fractures of rock mass in the grouting galleries of the left bank of a dam site area. Based on the measured results of fractures, the calculation method of permeability tensor is proposed and the relevant software using Visual Basic Language is developed. The merits of the software are easy to use and free of the trivial calculation due to visualization design. The software is used to calculate the permeability of fractures in the grouting galleries,and the results are validated. It is shown that the software can be used as a supplement for back analysis of water pressure experiment and can be used to provide scientific basis for the zoning of permeability of fractured rock mass and the optimization of curtain seepage prevention.
