| description | The embodiment of the invention discloses a method for predicting the ground surface vibration speed caused by cut blasting of a layered rock mass. The method is used for accurately predicting the ground surface vibration speed caused by tunnel engineering blasting construction of a layered rock mass structure. The embodiment of the invention provides a method for predicting the ground surface vibration speed caused by stratified rock cut blasting. The method comprises the following steps that firstly, the hole wall peak pressure of a single cut hole is calculated; constructing a hole wall blasting load caused by blasting of a single cut hole; calculating the radius of a crushing area and the radius of a fracture area after the single cut hole is blasted; calculating an equivalent elasticvibration load of single slotting hole blasting; determining an equivalent elastic boundary and an equivalent elastic vibration load of porous underholing blasting; constructing a semi-infinite layered rock mass multi-degree- |
