Stability analysis on surrounding rock mass of underground storage for LPG-Take a real project in Shandong Province as an example

  • 摘要: 地下储存液化石油气是各类地下工程中较复杂的一类工程。洞库围岩稳定性是工程成败的关键因素之一。洞库围岩稳定性一方面取决于洞库周边围岩应力集中的情况,另一方面取决于岩体强度和变形特征,其核心问题在于岩体完整性。可采用多参数综合分类法评价洞库围岩的稳定性,并用数值模拟分析液化石油气地下洞库拟开挖断面的应力场和位移场。定性分析及模拟验算表明:洞库围岩整体强度与抗变形能力均能满足稳定要求。
    Abstract: Underground storage of liquefied petroleum gas (LPG) is a complicated one of all kinds of underground engineering.Stability of the surrounding rock mass is one of important factors to make sure the success of the engineering.The stability of the surrounding rock mass depends upon its strength and deformation properties as well as the situation of stress convergence in it, and the key is the integrality of the rock mass.In this paper, the quality of the surrounding rock mass is estimated by the method of synthetic classification with multiple parameters.The stress and deformation fields in the section of the underground storage to be open are analyzed with numerical simulating.It is revealed that the strength and the anti deformation capacity of the surrounding rock mass as a whole are suitable to the demand of the project.
