摘要:选定我国江苏金坛盐矿为示范工程,通过深部盐岩的力学及蠕变试验,研究了深部盐岩的变形规律,建立
了深部盐岩溶腔的腔体变形三维计算模型。结合示范工程的具体地质条件,对深部地下盐岩溶腔的洞形、稳定性
及长期稳定性进行了数值模拟,研究了不同压力下溶腔容积的变化规律。通过现场储气库压腔试验,验证了计算
分析采用的参数合理性。研究结果表明,从地下工程稳定性方面来看,利用我国盐岩实施能源储备是可行的。

Abstract:As an example of a salt mining,the laws of deformation of salt rock in depth are investigated by the
mechanics and creep experiment of salt rock. The putational model of the deformation analysis of cavity
for salt rock is proposed. The optimization of cavity,stability,and long-term stability are studied on the basis of
the in-situ geological conditions;and the change laws of the volume of cavity are studied under different inside
pressures. The results show that the scheme of energy storage in salt rock is acceptable in China.
