摘要

地下水封石油洞库是利用饱水岩体密封性进行石油储存的方式，保持围岩完整性对地下水封石油洞库建造具有至关重要的作用。以我国首个在建的大型不衬砌地下水封石油储备库建设项目为背景，运用弹塑性理论，在室内岩石三轴试验基础上，研究了花岗岩地层大型不衬砌地下水封石油洞库围岩完整性参数的敏感性。研究表明：采用剪胀起始点作为岩体屈服点，可进行围岩完整性分析；洞库围岩松动范围和程度对摩擦角的敏感性大于对剪胀角的敏感性；洞室中墙应力分布变化对摩擦角的敏感性大于对剪胀角的敏感性；拱顶沉降对摩擦角的敏感性要大于对剪胀角的敏感性，水平收敛对摩擦角和剪胀角均具有较强的敏感性。研究成果对地下石油洞库围岩完整性评价以及水封系统设计提供了重要依据

Abstract

Underground crude oil storage caverns with the containment of groundwater is one of the methods for storage of crude oil. In the method

the containment property of saturated rock mass is taken advantage. Therefore

the integrity of rock mass is of great importance for the construction of underground crude oil storage caverns. Triaxial compression tests have been performed to determine the properties of the rock mass of a pilot underground crude oil storage caverns. The parameter sensitivity analysis of rock mass integrity is performed for a pilot underground crude oil storage caverns subject to construction. According to the test results

it is found that the integrity of rock specimen is damaged at the occurrence of volumetric dilation. The friction angle at this point could be used to determine the excavation induced loose zone in the construction of underground facilities. The extension of the excavation induced loose zone and the degree of loose in the zone are more sensitive to friction angle than to dilation angle. The change in stress distribution in pillar of caverns is more sensitive to friction angel than to dilation angle. The crown settlement is more sensitive to friction angle to dilation angle

but side wall convergence is sensitive to both friction angle and dilation angle. This study could be helpful in the assessment of rock mass integrity and in the design of containment system for underground crude oil storage caverns.
