Description
Technical field
The present invention relates to technical field of physical geography, and the prominent mud of rock zone gushing water is insulted more particularly, to a kind of Tunnel Passing rich water is rotten
Hazard prediction method.
Background technology
Trigger the judgement of the prominent mud problem of gushing water for Tunnel Passing rich water fault tectonic band, be built upon accurate to geological conditions
On the basis of really holding, to mud hydraulic pressure and the comparison of protection intensity.
And research of the engineering circles for mud gushing water problem of dashing forward at present, either concentrate on the detection of geological conditions or have in mind
In the research of prominent mud mechanism of water inrush, or the evaluation of outburst prevention measures is laid particular emphasis on, seldom propose system from the pre- measuring angle of prominent mud gushing water
The solution of system.
It is that stratum is extruded the superfine granule structural belt to be formed, postmenstruation under the conditions of high-temp plastic by regional structure that rock zone is insulted in gruel
Tectonic superimposition, transformation and underground water immersion, strength condition extreme difference.Prominent mud water bursting disaster is easily produced under high hydraulic condition.
Measure for protrusion-dispelling in the past mainly carries out information-based slip casting to tunnel surrounding, by grouting pressure, slip casting
The monitoring of amount judges surrounding rock consolidation effect, and the quality of detection borehole test country rock is used after curtain-grouting.It the advantage is that means
Directly, shortcoming is time-consuming, laborious, expensive, and easily causes omission, and individual lot can't detect.Moreover, in digging process,
Lack the prominent mud predicting means of effective gushing water.
The high-pressure water-enriched rotten rock zone of insulting of Tunnel Passing has high prominent mud analysis of possibility of water inrush, and current research emphasis is only in that
The control and inspection of slip casting effect, the means of use are mainly that information-based slip casting and drilling detect, and lack the Forecasting Methodology of system.
Measure is time-consuming, consumption money, lacks broad perspectives and easily causes omission.
The content of the invention
The present invention proposes that a kind of Tunnel Passing rich water is rotten and insults the prominent mud hazard prediction method of rock zone gushing water, relies on seismic reflection
Method, High Density Resistivity, local probing and echolation, the method that detection is pinpointed using timesharing, realize Tunnel Passing
The rotten purpose for insulting the prominent mud geological hazards prediction of rock zone gushing water of rich water.
The technical proposal of the invention is realized in this way：A kind of Tunnel Passing rich water is rotten to insult the prominent mud hazard prediction of rock zone gushing water
Method, comprise the following steps：
(1) constructing tunnel to rich water it is rotten insult rock zone before safe enough distance, utilize seismic reflectuon seismic noise detection is rotten to insult
Rock zone, meanwhile, acquisition system accurate location is marked, is prepared for detection next time, is analyzed in areal geology and exploration data
On the basis of, interpret rotten icepro rock zone specific position, occurrence, scale and property；
(2) intend passing through rotten icepro rock zone surface projection position in tunnel, surface exploration is implemented using High Density Resistivity, together
When indicate specific search coverage, detect prepare again for the later stage, using tunnel perimeter shoulder-bed resistivity (SBR) isogram, judge tunnel
The road country rock property of water-bearing everywhere.
(3) two kinds of geophysical prospecting method achievements contrast, and can accurately distinguish that rock zone relative tertiary location relation is insulted in tunnel with rotten
Crushed with structural belt, aqueous situation, accurate foundation is provided for country rock pre-reinforcement conceptual design；
(4) after the completion for the treatment of country rock pre-reinforcement, in hole former address carry out seismic reflection method quadratic probing, by detection data with
Previous result of detection contrasts, and judges that structural belt physical parameter improves situation, thus it is speculated that surrounding rock consolidation effect；
(5) implement second in earth's surface High Density Resistivity detection former address to detect, contrast, distinguish with detection data early stage
Surrounding rock consolidation region rock mass improves situation；
(6) live drill sampling, reinforcing body items physical parameter is tested, the prominent mud gushing water of country rock is analyzed by numerical modeling
Possibility, mud disaster of being dashed forward to Tunnel Passing gruel Ling Yan sections gushing water are predicted.
As a kind of perferred technical scheme, also comprise the following steps：(7) it is parallel, vertical in earth's surface former address in digging process
High Density Resistivity detection is directly carried out respectively in tunnel axis direction, is verified tunnel surrounding and is led in crack caused by excavation is possible
Aquaporin, is predicted to the prominent mud water bursting disaster that may further occur
As a kind of perferred technical scheme, also comprise the following steps：(8) as needed, back can be detected
Rejected region, carries out radar reinforcing detection in hole, and the possibility for mud gushing water of being dashed forward to it is clearly sentenced.
As a kind of perferred technical scheme, also comprise the following steps：(9) grouting and reinforcing is carried out to local seepage point.
Above-mentioned technical proposal is employed, beneficial effects of the present invention are：The present invention proposes a kind of timesharing fixed point Detection Techniques,
Performing, leading pre-supporting is forward and backward, and it is anti-to implement seismic wave to high-pressure water-enriched rotten icepro rock zone with same place outside hole in hole respectively
Penetrate method and High Density Resistivity detection and detection.Make full use of geophysical prospecting method it is quick, macroscopical, lossless the characteristics of, early stage, visit
The object of survey insults occurrence, position, scale and the property (emphasis is broken situation and the property of water-bearing) of rock zone, the weight of later stage detection for gruel
Point is tunnel surrounding consolidation effect, mainly judges to enclose by physical parameter (modulus of elasticity, Poisson's ratio, density, resistivity etc.)
Rock reinforcing scope and its uniformity.It is aided with local drill sampling, possible prominent mud projective water point is predicted.In digging process,
Using High Density Resistivity in earth's surface, radar reflectometry in hole, to because excavate stress field redistribution may caused by country rock
Rupture conduit pipe is detected, and possible prominent mud gushing water is predicted.
The present invention by seismic reflection technology, high-density resistivity technology be applied to the rotten detection for insulting rock zone tectonic property,
The evaluation of rear protecting structural strength is reinforced, while uses local drilling verification, and reflection of electromagnetic wave technology calamity in digging process
Harmful prediction, so as to reach the purpose of the prominent mud of system prediction gushing water, accurate foundation is provided for Construction Decision.The present invention is not thorough
The traditional drilling detection method of bottom substitution, but the utilization for the physical prospecting means for passing through system, reach and greatly reduce probing test, enter
And realize purpose that is succinct, quick, lossless, economically completing the prominent mud prediction of gushing water.
