Experiment number it is numerous influence through filling rock mass fissure seepage flow rule factor in, determine conspicuousness influence factor, so
Comprehensive test only is carried out to conspicuousness influence factor afterwards, not only causes experiment to catch principal element, easily draws the main of seepage flow
Rule, and by removing secondary cause, test period and cost have been saved, the difficulty of experiment is reduced, this experiment thinking is to this
Other experimental studies in field, it may have directive significance inwardly.
The present invention not only analyzes shadow of the single factor to seepage coefficient when handling the experimental data that comprehensive test is drawn
Ring, and by constructing multifactor and seepage coefficient formula, the effect of reflection various factors coupling through filling rock cranny to oozing
The universal significance rule of stream, there is the directive significance of reality to the supporting under the osmotic control and seepage environment of underground engineering.
It is methodological science that the present invention announces, rigorous, it can be done entirely to influenceing to fill insertion each factor of Seepage Flow in Fractured Rocks performance
The research in face, to the design of its support under the improvement of underground engineering seepage flow and seepage environment with implementing that there is directive significance.
