摘要地下岩体工程的迅速发展，使得地下洞室的围岩稳定性定量评估成为当前学界和工程界的重大关切。针对当前地下洞室围岩整体稳定性评估与分级尚无定量标准的现状，提出一套以评分制为基本框架、整合工程地质勘察、数值仿真、现场监测等成果的地下洞室硬质围岩整体稳定性定量评估方法，用于考虑围岩基本质量、地应力、不良地质构造、洞室规模与布置方式、施工方式与质量和地下水等因素对围岩整体稳定性的影响。基于该评估方法的基本原理和评估流程开发了地下洞室围岩稳定性云评估系统，可供使用者便捷有效地判别地下洞室的围岩整体稳定性状态并指导工程实践。将这一定量评估方法和云评估系统应用于多个地下洞室的围岩整体稳定性评估，验证了它们的可靠性和适用性。

Abstract：With the rapid development of underground rock mass engineering，the quantitative assessment of surrounding rock stability of underground caverns has become a major concern in the current academic and engineering communities. However，there is no quantitative standard for the assessment and classification of the global stability of surrounding rock in underground caverns. Therefore，this paper proposes a quantitative assessment approach for the global stability of the hard surrounding rock in underground caverns. The quantitative assessment approach integrates the results of engineering geological investigation，numerical simulation and field monitoring and takes the rating system as the basic framework. The quantitative assessment approach incorporates the influence of basic quality of surrounding rock，in situ stress，unfavourable geological structures，cavern dimension and layout，construction factors and groundwater on the global stability of surrounding rock. Based on the basic principle and the flow chart of this assessment approach，a cloud assessment system for the stability of surrounding rock in underground caverns is developed. The assessment system helps users to quickly and effectively determine the global stability of the surrounding rock in underground caverns and guides engineering practice. The quantitative assessment approach and cloud system are applied to assess the global stability of surrounding rocks in numerous underground caverns within many industries. The reliability and applicability of the approach and system are verified.
