摘要为了研究废弃矿硐储能库围岩的变形破坏特征和致灾机制，实现裂隙岩体地下储能库安全评估，研制地下空间储能防渗实验装置。基于相似理论，重新建立地下空间储能防渗实验的相似函数，获得实验设计依据，并使用模块化思想设计实验装置。实验装置具体包括大吨位加载框架、试样装载框架、液压动力源组件、水压加载模块、气压加载模块以及监测控制系统，采用有限元软件对大吨位加载框架进行模拟，确定其设计参数。大吨位加载框架搭配液压动力源组件能实现大尺度类岩石试样(尺寸500 mm×500 mm×500 mm)应力场模拟，配备的水压加载模块可实现地下空间抽水蓄能过程的模拟，利用气压加载模块模拟地下空间压缩空气储能全过程，监测控制系统可实现对装置整体监测和控制。利用该实验装置分别开展地下空间抽水蓄能、压缩空气储能循环实验，验证实验装置的准确性和可靠性。结果表明，该实验装置可以进行复杂应力条件下循环气压或水压荷载作用围岩力学实验，为废弃矿井储能工程安全施工和运营提供理论指导和技术支撑，为废弃矿井资源开发、利用提供重要的实验测试平台。

Abstract：An experimental device for energy storage and seepage prevention in underground space was developed to study the deformation，damage characteristics and disaster-causing mechanism of the surrounding rock of an abandoned mine energy storage reservoir，and perform a safety assessment of the underground energy storage reservoir in the fissured rock body. The similarity function of the underground space?s energy storage and seepage prevention was reestablished based on similarity theory. The experimental design basis was obtained and the experimental setup was created using the modular design idea. The experimental device includes a large-tonnage loading frame，a specimen loading frame，hydraulic power source components，a water pressure loading module，an air pressure loading module and a monitoring and control system. Finite element software was used to simulate the large-tonnage loading frame and determine the design parameters. The large-tonnage loading frame with a hydraulic power source assembly enabled the simulation of the stress field of large-scale rock-type specimens(500 mm×500 mm×500 mm). It was equipped with the water pressure loading module that enabled the simulation of pumped storage processes in the underground space. Simulation of the whole process of compressed air energy storage in the underground space was performed using the air pressure loading module. The monitoring and control system realized the overall monitoring and control of the device. The experimental device was utilized to implement pumped energy storage tests in the underground space and compressed air energy storage cycle tests to verify the accuracy and reliability of the experimental device. The results show that the experimental device can be used in experiments on the mechanics of peripheral rocks under the action of cyclic air and water loading under complex stress conditions. It can provide theoretical guidance and technical support for the safe construction and operation of abandoned mine energy storage projects and serve as an important experimental test platform for the development and utilization of resources in abandoned mines.
