Method and device for predicting rock burst in tunnel, and storage medium and system

The application provides a method and a device for predicting rock burst in a tunnel, and a storage medium and a system. The method includes the steps of: acquiring Hoek-Brown rock mass strength of surrounding rocks at a to-be-tested depth and the maximum ground stress of an in-situ stress field in the direction being vertical to tunnel axis; calculating a predicted index of rock burst, wherein the threshold value of the predicted index of rock burst is the ratio of the Hoek-Brown rock mass strength to the maximum ground stress of the in-situ stress field in the direction being vertical to tunnel axis; and predicting rock burst level according to the threshold value of the predicted index of the rock burst. 本申请提供种隧道岩爆预测方法、设备、存储介质和系统，隧道岩爆预测方法，其特征在于，包括以下步骤：获取待测深度处围岩的Hoek-Brown岩体强度和原岩应力场垂直洞轴线方向的最大地应力；计算岩爆预测指标值，所述岩爆预测指标界限值为所述Hoek-Brown岩体强度与所述原岩应力场垂直洞轴线方向的最大地应力的比值；根据所述岩爆预测指标界限值的大小，预测岩爆等级。
