天荒坪抽水蓄能电站地下厂房内安装有６×３００ＭＷ的混流可逆式蓄能机组，悬式发电电动机。地下厂房的结构面临激振频率高、结构层高大、上部受力、基础薄弱等对结构振动不利的头重脚轻的局面。为此，采取了局部加强、提高弹模、改进设备基础受力条件、尽量利用围岩受力等一系列措施，并针对不同的结构布置型式，组织了两阶段多个模型多种工况的整体结构三维有限元动、静力分析，从而掌握了结构的受力特性，结构设计较为圆满。
Tianhuangping Pumped Storage Power Station underground power plant installed 6 × 300MW Francis reversible accumulator units, suspension generator motor. The structure of the underground powerhouse is facing the top-heavy situation which is unfavorable to structural vibration due to high vibration frequency, tall structural layer, upper stress and weak foundation. To this end, a series of measures such as local strengthening, improving the elastic modulus, improving the basic mechanical stress conditions of the equipment, using the surrounding rock as much as possible, and adopting different types of structural arrangements have been adopted to organize various working conditions of multiple models in two stages The overall structure of three-dimensional finite element analysis of dynamic and static, so as to grasp the structure of the force characteristics, structural design more satisfactory.
