中文摘要：

为解决地下水平盐岩储库的稳定性问题,在三剪能量屈服准则和试验研究的基础上,建立一个新的基于洛德角和应力的全应力状态的扩容准则。以建立的准则为判据,在不同轴比、不同侧压系数条件下,对常见的水平椭圆柱形的盐岩储库腔壁稳定性进行评价,最终确定储库的最佳轴比及其运营的极限气压范围。将计算结果与Kerry DeVries准则的计算结果进行对比,结果表明：该准则为确定地下水平盐岩储库运营时的极限气压提供了行之有效的理论方法。

英文摘要：

A new criterion of salt dilation considering Lode angle and the total stress states on the basis of the yield criterion of triple shear energy was developed to investigate the stability for underground horizontal gas storage in I）edded salt formations. The theoretical analysis of stress distribution was carried out to a salt cavern with elliptical cross-section and the state of stress along the wall of the salt cavern was discussed. The wall stabilities of salt caverns with different ratios of long-axis to short-axis and lateral pressure coefficients are estimated with the new dilation criterion. The best cavern shape for different lateral pressure coefficients and the range of pressure limits for the operation of salt cavern are thus determined. The results from the new dilation criterion are consistent well with the measured data.
