Description
Technical field
The present invention relates to geological exploration techniques, more particularly to a kind of search of the rock mass discontinuity based on high definition drilling colour TV
Method.
Background technology
In rock mass extensive development the origin cause of formation is various, scale not etc., the different structural plane of character, the presence of various structural planes breaks
The globality of rock mass is broken, directly affects the mechanical property and deformation failure models of rock mass.Therefore, one in engineering geological investigation
Important content is exactly to find out rock mass discontinuity --- the developmental state in I~IV level structure face and the V level structure face grown up, so as to
Its adverse effect to engineering of subsequent evaluation.
Find out rock mass discontinuity developmental state, conventional method is only capable of solving I~III level structure larger, that character is poor
Face, it is mainly surveyed and drawn and explored with surface geology adit and discloses to analyze the space developmental state of structural plane, and drilling only plays auxiliary
Judgement acts on.Conventional method is completely dependent on exploration adit, and prospecting input is big, cycle length, drills because not can determine that structural plane occurrence
In trend or tendency parameter, only help out in judgement, to a plurality of tomography at the same time develop or tomography character it is relatively good
There is the possibility of erroneous judgement toward contact in position, and this method cannot find out the space developmental state in IV level structure face, cannot more search
V level structure face of rope.In recent years, with the extensive use of high definition drilling Color TV Technology, the colour TV generation three-dimensional electronic rock that drills is utilized
Core, can directly obtain structural plane occurrence and trait information by interpretation software, this is developed for the space of search rock mass discontinuity
Situation provides possibility.In current engineering practice, also without one kind can search for rock mass discontinuity and it is easy to operate, reliability is high
Searching method.
The content of the invention
The defects of the technical problem to be solved in the present invention is to be directed in the prior art, there is provided one kind is color based on high definition drilling

If 4.3) 4.1) in the range of the allowable deviation of setting, judge locus one with 4.2) gained distance
Cause, be transferred to step (5), it is not same otherwise to judge two-strip structure face；
5) character pair ratio；
Character contrast is carried out to the structural plane that step 4) obtains, judges that two-strip structure face is if character is same or similar
Same, it is not same otherwise to judge two-strip structure face.
By such scheme, the method that an identity distance is calculated in the step 4) is：According to the space plane side in step (2)
Journey, space any point (x1,y1,z1) to the distance dist of the structure facial plane be：
By such scheme, in the step 3), determine occurrence contrast when tolerance scope pass through including research area it is more
Combined factors including the occurrence error that table structure surface development form, the distribution of exploration exposure point, drilling colour TV are read determine.
By such scheme, in the step 4), determine that the scope of tolerance during the contrast of locus passes through including research
Combined factors including the occurrence error that area's majority structural plane developmental morphology, the distribution of exploration exposure point, drilling colour TV are read determine.
For example, for the ideal structure face of the straight development of broken face, two structural planes of point distance 50m are disclosed, if
1 ° of (tendency) angular deviation is moved towards, then range deviation about 0.9m.Assuming that certain research plot structure face is mostly straight development, the spacing of wells
General about 30m, tendency deviation can use 10 °, and inclination deviation can use 5 °, and range deviation can use 10m.

Between position, property contrast, determine two prospecting point disclose a structural planes whether belong to same structure face.
2) present invention takes full advantage of the structural surface information that drilling discloses, and overcomes the limitation of conventional method, not only expands
Big search range, and the reliability of search is improved, have the characteristics that easy to operate, reliability is high.
3) the method for the present invention is searching structure face due to taking full advantage of hole structure face character and occurrence information, evaluation
Adverse effect of the structural plane to engineering, there is provided one is saved time, the scheme of investment reduction.
4) present invention establishes structural plane space plane geometric equation, devises structure on space measurement data base
Face occurrence contrast and the formula algorithm of locus contrast, for the application of exploitation rock mass structure faceted search mass processing in next step
Program, has established most important basis.
