Description
Technical field
The present invention relates under the underground works complex geological conditions such as a kind of tunnel or tunnel based on the technological high-resolution imaging method for forecasting advanced geology of resistivity CT; Specifically a kind of relating to, adopt resistivity CT technology to carry out stereopsis and three-dimensional cover type data acquisition in tunnel or tunnel; And result of detection carried out the decipher of three-dimensional total space resistivity inversion, realize the meticulous method of detecting of workplace front geological condition.
Background technology
Along with the quickening of China's infrastructure construction process, will build the underground workss such as tunnel, tunnel of more growing up in fields such as traffic, water conservancy and hydropower and exploitation of mineral resources.These underground workss generally have distinguishing features such as buried depth is big, hole line length, complicated hydrogeological conditions, and construction geologic prospect work in earlier stage is difficult to investigate thoroughly hydrogeological condition along the line in addition, causes in construction, will facing many geologic hazards.Wherein prominent (gushing) water, prominent (gushing) mud disaster are one of main geologic hazards, and at home and abroad in the underground works serious accident, prominent (gushing) water, prominent (gushing) mud disaster all occupy the prostatitis on death toll and frequency.
According to statistics; In the process of construction of Chengdu-Kunming Railway Line, Qun Dynasty's line, the wide multiple line of weighing apparatus; Because of accounting for shut down time that the hydrology, geological problem caused 1/3～1/4 of total time of construction, gush sand in the construction of Yuhuai Railway Yuanliangshan Tunnel, water burst reaches tens of times more than, create greater casualties; Should in August, 2007 large-scale gushing water accident take place in tunnel, wild three pass of ten thousand railways, the gushing water amount is up to 5 * 10
4m
3/ d causes 10 people dead; Red deer cyanines tunnel gushing water causes 15 people dead, instantaneous water yield be world's railway tunnel; Silk screen hydroelectric pivotal project auxiliary tunnel is positioned on the Yalongjiang River master stream silk screen A Bend in the River in Sichuan Province, the about 17.5km of total length, and maximum buried depth reaches 2375m, high hydraulic pressure of the 10MPa that is run in the constructing tunnel and 7m
