地下水封储油洞库岩体力学参数试验研究
|
摘要
目前,国内正在进行二期战略石油储备地下水封储油洞库的建设。地下水封洞库工程中,岩体力学参数的准确选取对洞室结构稳定性的计算具有重要的作用。通过在某地下水封洞库中进行的岩体结构面直接剪切试验得到的试验结果,和Barton等提出的JRC-JCS模型、Q值估算变形模量经验公式以及Hoek-Brown强度准则计算的结果进行对比和分析,发现用经验估算方法以及Hoek-Brown强度准则计算的结果和现场原位试验所得数据基本一致,经验估算方法和Hoek-Brown强度准则可以应用到地下洞库工程建设中,是确定地下洞库岩体力学参数简便适用的方法。
At present,the construction of water sealed underground petroleum storage caverns is ongoing for the second phase of strategic petroleum reserve in domestic. In the engineering construction of the caverns,the correct selection of rock mechanical parameters is important for the stability calculation of cavern structure. The results obtained from structural plane direct shear tests of a underground storage cavern,were compared and analysed with those acquired from adapting JRC-JCS model and deformation modulus empirical formula through Q value which was put forward by Baton etc. as well as Hoek-Brown criterion. It was found that the data obtained with experience estimation method and Hoek-Brown criterion was almost the same with in situ test data. This indicates that experience estimation method and Hoek-Brown criterion can be applied to the engineering construction of underground storage caverns. They are simple and practical methods to determine the rock mass mechanical parameters in water sealed underground storage caverns.
