Abstract

The invention discloses an earthquake wave and electromagnetic wave joint inversion tunnel forecast device, a tunnel boring machine and a method. The earthquake wave and electromagnetic wave joint inversion tunnel forecast device comprises composite wave detectors, shock rods, electromagnetic emission rods,concentrators and a controller; the shock rods are used for sending earthquake wave signals;the electromagnetic emission rods are used for sending electromagnetic wave signals, the shock rods and the electromagnetic emission rods are connected with the controller through first concentrators, or the shock rods and the electromagnetic emission rods are respectively connected with the controller through the first concentrators and second concentrators; motivation command emitted through the controller can be transmitted to the electromagnetic emission rods or the shock rods; the composite wave detectors synchronously receive electromagnetic wave signalsand the earthquake wave signals,the composite wave detectors are connected with the controller through third concentrators, and the received signals of the composite wave detectors can be transmitted to the controller after being concentrated in third concentrator positions.

Description

technical field [0001] The invention relates to the direction of advanced geological prediction in tunnel engineering, in particular to a tunnel prediction device, a roadheader and a method for joint inversion of seismic waves and electromagnetic waves. Background technique [0002] With the rapid development of my country's transportation technology, my country has become the country with the largest and most difficult tunnel construction in the world. The difficulty of tunnel construction has shifted to the karst area with complex geology in the west and the super-long sea-crossing area in the east. During tunnel construction, engineering geological conditions are extremely complex, and engineering disasters such as tunnel water inrush, mud inrush, and landslides are prone to occur, seriously threatening the safety of construction personnel and property, and affecting construction progress. Advanced geological forecast is based on the existing geological data to detect, an...
