摘　　要：类比于其他工程建筑物,深埋地下厂房轴线选择应充分考虑工程区最大主应力方向及厂房区域主要结构面(断层、节理)的发育规律,尽量使厂房轴线方向与最大主应力呈小角度相交或平行、与岩体主要结构面(断层、节理)大角度相交,并且在保证厂房上下游及两侧边墙和顶拱围岩稳定性前提下,兼顾建筑物功能、施工、运行等因素,达到建设工程与自然环境协调统一的目的。Analogous to other engineering buildings,the axis selection of a deep-buried underground powerhouse should fully consider the direction of the maximum principal stress in the engineering area and the development law of the main structural planes(faults,joints)in the plant area,and try to make the axis direction of the plant and the maximum principal stress appear as Intersect or parallel at a small angle,intersect with the main structural planes(faults,joints)of the rock mass at a large angle,and take into account the function,construction and operation of the building under the premise of ensuring the stability of the upstream and downstream of the plant and the side walls and top arch surrounding rock And other factors to achieve the goal of harmonization between the construction project and the natural environment.
