Head, limestone aquifer specific capacity, limestone aquifer infiltration coefficient.
According to this 7 factors, research object is divided into tri- levels of A, B, C, seat earth limestone fragility is final
Purpose, in this, as simulated target layer (A level)；Water-resisting floor, geological structure, floor water-bearing rock directly affect gushing water
Property, but its influence mode also needs relative because usually embodying by other, this is the middle transition ring of processing problem
Section, is the rule layer (B level) of model；Lithology combination, impermeable layer thickness, tomography distribution, tomography scaled index, hydraulic pressure, unit
Water yield, infiltration coefficient are specific Dominated Factors, directly decision Water Inrush possibility, constitute (C layers of the decision-making level of model
It is secondary).
Step B relies on hierarchical structure analysis model, establishes fuzzy consensus discrimination matrix；
According to the factor for influencing exploiting field bottom plate limestone gushing water, using " collection expert point rating method ", according to 0.1~0.9 scale
Marking is compared to the adjacent level of model two-by-two, establishes fuzzy consistent judgment matrix.
B level may be expressed as: the fuzzy consistent judgment matrix of A level
C1、C2To B1Fuzzy consistent judgment matrix may be expressed as:
