基于云模型的深埋隧洞岩爆灾害预测研究

Prediction research of rockburst disaster in deep tunnel based on cloud model

岩爆是高应力地下洞室施工中对施工中的人员和设备威胁极大的工程地质灾害。文章基于以往学者研究成果,提出基于云模型的岩爆等级评价方法,工程实测数据检验结果显示,该模型具有较高的预测精度,可以用于相关工程设计施工中的岩爆预测。文中利用云模型对辽宁省大风口水库输水隧洞岩爆问题进行了预测分析,对该工程的施工建设具有一定的指导价值。

Rockburst is a serious engineering geological hazard that threatens the personnel and equipment in the construction of high-stress underground caverns. Based on the previous research results of scholars, this paper puts forward a rock-burst grade evaluation method based on cloud model. The test results of engineering measured data show that the model has high prediction accuracy and can be used for rockburst prediction in related engineering design and construction. Finally, the cloud model is used to predict and analyze the rock burst in the water conveyance tunnel of Dafengkou reservoir in Liaoning Province, which has a certain guiding value for the construction of the project.
