我国将要兴建实施较大规模战略石油储备地下库面临一系列工程地质问题和挑战。为更好地服务于库址选择和规划,为工程设计和施工提供地质依据,本文在总结归纳已有工程实例和分类基础上,结合作者已经完成的两个石油战略储备基地选址评价,提出和分析了与地下油库有关工程地质问题及相应对策。
Large - scale rock caverns for storage of oil and gas are to be constructed in China. A number of engineering geological issues and challenges have come out. This paper presents a review of some case examples of storage caverns and investigations in China. It further describes two case studies that have been carried out by the authors. Based on these studies, the paper classifies engineering geological issues and associated investigations. It summarizes some engineering measures that have been adopted in practice. The findings in this paper can be useful for site selection and assessment, plan and design of underground rock caverns for storage of oil and gas.
