Three-dimensional fine imaging system and method based on drilling geological radar technology

Abstract

The invention discloses a three-dimensional fine imaging system based on a drilling geological radar technology. The system comprises devices, such as a radar transmitting antenna, wherein the radar transmitting antenna is transmitted into a bore through a radar antenna transmitting device; a radar receiving antenna moves along a measuring line on a tunnel work area surface through a radar antenna driving device; the radar transmitting antenna and the radar receiving antenna are connected with a radar host machine; the radar host machine is respectively connected with a storage battery and a computer; the radar antenna transmitting device and the radar antenna driving device are connected with a control host machine; and the control host machine is connected with the storage battery through a power wire and controls the antenna to transmit and the driving device. The invention also provides a stereo three-dimensional observing method. Three-dimensional detection on surrounding media of the bore is realized by matching the method with a 'transmitting, receiving, circulating and detecting' way based on coverage observation for multiple times, and by a speed imaging method based on constrained reversion and a three-dimensional interpolation method, and the three-dimensional fine detection on the geological status in front of the tunnel work area surface is realized.

Description

technical field [0001] The invention relates to a three-dimensional refined imaging system and method, in particular to a three-dimensional refined imaging system and method based on borehole geological radar technology in tunnel construction. Background technique [0002] After entering the 21st century, a large number of major infrastructure projects such as railway and highway traffic projects, water conservancy and hydropower projects have been put on the construction agenda, which has greatly promoted the construction of tunnel projects. By the end of 2010, about 450 kilometers of tunnels have been built every year in my country's transportation, hydropower and other fields, and more than 10,000 kilometers of railway and road tunnels have been built. It is estimated that only my country's railway tunnel construction will reach "two ten thousand" (10000km / 10000 seats) in 2020. my country is already the country with the largest scale and difficulty in tunnel construction...
