摘要

针对压缩空气储能人工硐室储气库抗抬升计算方法不统一、安全评价标准不完善的工程难题，本文系统梳理了刚性锥、刚性锥-抗剪、刚性锥-抗拉、垂直-剪切四种极限平衡模型的计算原理与适用边界，构建了包含超载系数、循环荷载系数、岩体完整性系数的分项式抗抬升安全系数框架。结合工程案例与数值模拟，深入探究了不同计算模型下储气库抗抬升安全系数随埋深、运行压力的演变规律，分析了不同埋深工况下储气库围岩的位移特征与塑性区分布规律。研究结果表明：同等埋深条件下，刚性锥-抗剪、刚性锥-抗拉模型的计算结果偏于激进，刚性锥模型与垂直-剪切模型的计算结果相对较小；在压缩空气储能电站日循环运行工况下，Ⅰ～Ⅱ类、Ⅲ类、Ⅳ类及以下围岩对应的储气库抗抬升安全系数推荐值分别为1.98、2.15、2.48；随埋深增加，储气库围岩位移量与塑性区范围均呈现先快速降低后逐渐稳定的特征；当覆土厚度由1倍硐室内径提升至7倍硐室内径时，围岩位移由96.16 mm降至7.20 mm，围岩塑性区体积占比由40.3%降低至10.1%，此时硐室群效应基本消散，继续增大覆土厚度，对抑制围岩变形、控制塑性区扩展的改善效果有限。

Abstract

To address the engineering challenges related to the lack of uniformity in the calculation methods for resisting uplift in compressed air energy storage chambers

as well as the inadequacy of safety evaluation standards

this paper systematically analyzes the calculation principles and applicable limits of four types of limit equilibrium models: rigid cone

rigid cone with shear resistance

rigid cone with tensile resistance

and vertical-shear model. It establishes a framework for calculating the safety factor against uplift

incorporating factors such as overload coefficient

cyclic load coefficient

and rock mass integrity coefficient. Through engineering cases and numerical simulations

the paper explores how the safety factor against uplift varies with depth and operating pressure under different calculation models

and it analyzes the displacement characteristics and distribution of plastic zones in the rock surrounding the storage chamber at various depths. The results show that

at the same depth

the calculation results obtained using the rigid cone with shear resistance and rigid cone with tensile resistance models are on the higher side

while those from the rigid cone model and the vertical-shear model are relatively lower. Under the daily cyclic operating conditions of power plants

the recommended safety factors against uplift for rock masses of categories Ⅰ~Ⅱ

Ⅲ

Ⅳ

and below are 1.98

2.15

and 2.48

respectively. As the depth increases

both the displacement of the rock surrounding the storage chamber and the size of the plastic zone decrease rapidly before stabilizing. When the thickness of the overburden increases from 1 time the inner diameter of the chamber to 7 times that diameter

the maximum vertical displacement of the rock drops from 96.16 mm to 7.20 mm; at this point

the effect of the chamber cluster essentially disappears

and further increasing the overburden thickness has only a limited impact on reducing rock deformation and controlling the expansion of plastic zones.
