摘要
黄岛地下水封洞库洞室群规模大,且采用平行布置,洞室主轴线布置对洞室群稳定性至关重要。从地应力与结构面角度出发,运用有限差分法分析了洞库区地应力对洞室群主轴线布置的影响规律。在此基础上综合考虑结构面与地应力探讨了洞室群合理主轴线方位。
Because the cavern group in Huangdao underground water-sealed cave storage have large scale, and adopts the parallel arrangement, the arrangement of main axis in cave storage is important to the stability of cav- ern groups. From the view of ground stress and structure plane, the law of ground stress influencing to main axis arrangement are analyzed by FEM. On the basis, the main axis azimuth of cavern groups is discussed on com- prehensively considering the ground stress and structure plane.
