摘要

摘要: 水封性评价是地下水封石油洞库建设的关键科学问题。围绕地下石油洞库水封性评价,提出了地下水封石油洞库水封性评价的水文地质概念模型,总结了水封性评价中地下水、岩体性质与地质环境和洞库工程特征3个方面基础数据,分析了三者之间关系;分析了经验法、数值分析法和试验法三大类评价方法的特点和对应的适用范围,提出了评价方法“三适应”选用原则：评价方法与建设阶段、评价目标和参数要求相适应,提出了水封性评价流程,分析了不同评价阶段所应采用评价方法和重点的评价内容;以具体工程为背景,介绍了评价方法体系的应用情况,并着重介绍了经验法、裂隙网络法和现场试验法在水封性评价中的使用情况。研究成果对提高地下水封石油洞库水封性评价水平具有重要参考价值。

Abstract: One of the important scientific issues for the construction of underground storage caverns is the assessment of containment properties of the caverns. It is aimed to develop a system of methods for the assessment of containment properties of the caverns. A conceptual hydrogeological model for the assessment is proposed. The required information on groundwater, rock mass properties and geological conditions and the engineering characteristics of caverns are summarized. The relationship among the three aspects is analyzed. The catalogues, application fields and characteristics of empirical, numerical and experimental methods are analyzed. The principles for the selection of methods are proposed for the assessment. That is, a favorable method is suitable to the construction stage, assessment object and parameter requirements. A procedure of containment property assessment is proposed. The methods and contents for different stages of the assessment are recommended. A case study is performed to show the applicability of the system. The empirical method, discrete fracture network modeling and experimental methods are used to assess the containment properties of the project. This study may provide an important reference for the construction of underground storage caverns with groundwater curtaining system, and a critical benchmark for the study on seepage behaviors of jointed rock mass.
