Occurrence or fold building core portion positional information；Certainly, those skilled in the art can also go out root by software programming, self-developing
According to region topographic map generation treat domain for assessment digital elevation model, according to regional geologic map determine treat it is variant in domain for assessment
Each attitude of stratum of opening position or the software algorithm program of fold building core portion positional information, these Processing Algorithms are all ripe show
There is technology.
3) treat domain for assessment and carry out grid division, each grid cell for treating to divide in domain for assessment is considered as a number
According to unit, ground slope aspect and ground slope corresponding to each grid cell are extracted respectively from the digital elevation model for treat domain for assessment
Degree, from treating in domain for assessment that extraction is each respectively in each attitude of stratum of variant opening position or fold building core portion positional information
Dip direction and stratigraphic dip corresponding to grid cell.
In the step, geographic areas size corresponding to each grid cell obtained by domain for assessment progress grid division is treated
Desirably no more than 100m × 100m, slope stability evaluation is carried out more reasonably to ensure to treat regional area side in domain for assessment
Accuracy, and after the grid cell total quantity of domain for assessment gained after grid division, then according to the gross area for treating domain for assessment
And geographic areas size corresponding to each grid cell and determined.After treating domain for assessment and carrying out grid division, by
In each grid cell for treating to divide in domain for assessment is considered as into a data cell, therefore treat each grid in domain for assessment
The parameter extraction of cell can use different modes of operation；Treated for example, can be directed in domain for assessment in each grid cell
A specified location point, from the digital elevation model for treat domain for assessment extract relevant position point ground slope aspect and ground slope
Degree, from treating to extract relevant position in each attitude of stratum of variant opening position or fold building core portion positional information in domain for assessment
The dip direction and stratigraphic dip of point, as ground slope aspect, ground line gradient, dip direction and stratum corresponding to corresponding grid cell
Inclination angle, so as to obtain treating each grid cell each self-corresponding ground slope aspect, ground line gradient, dip direction and ground in domain for assessment
Inclination layer；Or each grid cell treated in domain for assessment can also be directed to, from the digital elevation model for treating domain for assessment
Extract the ground slope aspect of each position point and ground line gradient in corresponding grid cell and try to achieve ground slope aspect average and ground slope respectively
Average is spent, it is corresponding from treating in domain for assessment to extract in each attitude of stratum of variant opening position or fold building core portion positional information

The mode of row parameter extraction, operation is more easy, and small for the grid of division area sufficiently small (being not more than 100m × 100m)
For area, the side slope characteristic information difference of each position point is little in its region, therefore utilizes any one position in grid cell
The side slope characteristic information of point has been enough accurately to characterize the overall side slope quality event of corresponding grid cell.
4) each grid cell for treating ground line gradient >=λ or stratigraphic dip >=λ in domain for assessment is directed to, is asked for respectively wherein
The absolute value of the ground slope aspect of each grid cell and the difference of dip direction, the slope difference of inclining as corresponding grid cell；λ is pre-
If angle threshold.
The step is to calculate the slope difference of inclining of each grid cell, to as the follow-up spy for carrying out slope stability evaluation
Levy parameter.But when calculating, by an angle threshold λ set in advance, to ground line gradient<λ or stratigraphic dip<λ region is entered
Go and screened out processing, each grid cell that only have selected ground line gradient >=λ or stratigraphic dip >=λ is calculated；Herein, in advance
If angle threshold λ preferred value be 3 °~8 °, that is, think ground line gradient<λ or stratigraphic dip<λ region has preferable
Slope stability, therefore without additionally carrying out slope stability evaluation；Thus, just can reduce to slope difference operation processing of inclining
Amount of calculation, help to improve evaluation treatment effeciency to a certain extent.
