山体内废弃洞室用于压缩空气储能电站储气可行性研究
Feasibility Study of Utilizing Abandoned Caverns in Mountains for Compressed Air Energy Storage
摘要
Abstract
The use of abandoned caverns not only addressed the issue of resource idleness after engineering decommissioning but also provided a low-cost site selection solution for large-scale energy storage,aligning with the demand for clean energy storage under the"dual carbon"goals and demonstrating significant environmental benefits.Based on a compressed air energy storage project in Northwest China,the influence of storage pressure and cavern shape on the deformation of surrounding rock was investigated.The displacement and plastic zone variation patterns of the surrounding rock were obtained,and the failure surface shape of the overlying rock mass above the cavern was analyzed.This analysis confirmed the rationality of tunnel-shaped caverns in terms of the safety of the overlying rock mass.The potential failure modes of the overlying rock mass were determined based on the plastic zone.Furthermore,a conical model considering the inherent strength of the rock mass was established using the limit equilibrium method to analyze the stability of the cavern.The maximum storage pressure was determined to be 8 MPa,providing a reference for engineering design.关键词
