Abstract

The application discloses a vibration detection method and related equipment for drilling and blasting construction in the transitional section of soft and hard surrounding rocks. Vibration data in the rock, obtain vibration data before construction, during construction and after construction; draw vibration data over time; collect displacement data of support frame; calculate displacement rate of support frame; construct 3D dynamic view ; Collect the pressure data of the pressure sensor array; mark the coordinates of the pressure sensor unit whose pressure change per unit time exceeds the set pressure value on the three-dimensional dynamic view; collect the water content data in the surrounding rock; generate a dynamic distribution map of the water content, And superimposed in the three-dimensional dynamic view; monitor the state of the support frame and surrounding rock; adjust the parameters of the drilling and blasting equipment to adjust the vibration impact of the drilling and blasting construction on the surrounding rock in the transitional section of soft and hard surrounding rock. It can detect the vibration of drilling and blasting construction in multiple directions.

Description

technical field [0001] The present application relates to the field of survey technology, in particular to a vibration detection method and related equipment for drilling and blasting construction in transitional sections of soft and hard surrounding rocks. Background technique [0002] Long and long tunnels are generally buried deep, and often pass through special rock formations such as water-rich, weak, fractured, and broken, which pose a high safety risk. The common construction method of tunnel construction includes drilling and blasting construction. During the drilling and blasting construction process, corresponding vibration will be generated. The vibration will have a certain impact on the stability of the surrounding rock, which will easily cause the internal stress of the surrounding rock to be unbalanced, especially in the transition between soft and hard surrounding rock. Any segment, instantaneous or continuous vibration may cause the collapse of the surroundi...
