| Abstract:This text introduce a new tunnel comprehensive geological prediction system of USEP, it uses Synthetical parameter method to predict geo鄄
logical features ahead of construction face. Synthetical parameter is wave velocity and resistivity. Wave velocity detection uses combined system of angle
offset and position offset, and resistivity detection uses overlapping circle line of TEM to scan at the tunnel face, Synthetical parameter and space geolog鄄
ical prediction can be achieved at final. The research team developed a USEP system which was applied to construction of the NANCUN tunnel on the No.
108 national highway to show work principle and effect of tunnel Synthetical parameter and space geological prediction, and the necessity of tunnel compre鄄
hensive geological prediction using wave velocity and resistivity under complicated geological condition was summarized. It has extensive guide role on ad鄄
vanced geological prediction of tunnel and underground engineering construction. |
