Description
Technical field
The present invention relates to the dangerous determination methods of landslide control engineering technical field, more particularly to a kind of rock landslip
And its application.
Background technology
Red beds is clastic deposited sediments stratum of the outward appearance using red as dominant hue, is distributed widely in the southwest, northwest, China in China
In and South China, wherein it is the Sichuan Basin to be distributed most wide, area is up to more than 260,000 square kilometres.Based on Red Bed is landslide easily hair
Area, often occurs numerous landslide disasters in rainy season, and the natural calamity that rock landslip, which is even more one of which, can not be ignored.Rock
Matter landslide is a kind of generation in mountain area or the natural phenomena of slope of highway.Rock landslip occur after, produce slip rock mass and its
The upper face soil body moves under hillside or roadside, becomes silted up and buries and impact Architectural Equipment, the highways such as neighbouring residenter house, factory
Deng causing greatly to destroy.
Rock landslip generally requires possess three conditions:One is advantageous for occurring the orographic condition of rock landslip;
Second, there is weak structural face in rock stratum, such as the siltized intercalation in sand-mud interbed;Third, abundant rainfall, rainwater are entered by crack
The generation of weak structural face and final induced landslide.These condition combined influences simultaneously determine the stability of slopes.Wherein, landform bar
Part includes to the influence factor of rock landslip:Ramp slope, slip mass upside steep slope topography and the slip mass folder of potential slip mass
Canyon topography among left and right.At present, research of the domestic and foreign scholars to the orographic condition for formation of coming down focuses primarily upon domatic
The research of the gradient, it is the simple data statistics to its distribution rule, does not further investigate its inherent mechanism.
Publication No. CN 104299367A, publication date are that the Chinese patent literature of on 01 21st, 2015 discloses one kind
Landslide disaster multistage comprehensive monitoring method for early warning, it is characterised in that it comprises the following steps:(1) number is monitored by historical record
According to Landslide Deformation damage model test, calculate landslide monitoring early warning threshold limit value;Determine to grind according to each index critical exponent
Study carefully the possibility whether area has landslide to occur;(2) if monitoring numerical value is more than critical value;According to each landslide occurrence index, it is determined that
Come down the possibility size that the place that may occur and landslide occur, and delimit early-warning and predicting grade;(3) level Four early warning and pre- is determined
Alert boundary region;(4) early warning result is issued, in combination with the precautionary areas mass presdiction and disaster prevention network system, directly notice monitors person liable,
Carry out and take precautions against natural calamities, keep away calamity preparation.
Landslide disaster multistage comprehensive monitoring method for early warning disclosed in the patent document is, it is necessary to which a large amount of history for generation of coming down are recorded
Monitoring Data is recorded, then by Landslide Deformation damage model test, calculates landslide monitoring early warning threshold limit value;Further according to each index
Critical exponent determines the possibility whether research area has landslide to occur, although the landslide factor of analysis is more, to influenceing landslide
Another key factor terrain factor analysis is very few, more without quantitative terrain factor computational methods, causes whole landslide early warning
Accuracy, it is not particularly suitable for the dangerous judgement of Based on Red Bed rock landslip.
The content of the invention
The present invention in order to overcome above-mentioned prior art the defects of, there is provided a kind of dangerous determination methods of rock landslip and its
Using comprehensively the present invention considers the influence of topography factor of rock landslip, and rock landslip danger is accurately divided in a manner of quantitative
Property region, greatly improve the dangerous accuracy judged of rock landslip, there is good landslide early warning effect.
The present invention is achieved through the following technical solutions:
The dangerous determination methods of a kind of rock landslip, it is characterised in that comprise the following steps:

Dangerous judgement.
The principle of the present invention is as follows:
Upper steep lower slow landform is advantageous to rainwater and enters potential slip mass by slip mass top crack, and then causes rock stratum
The gradual saturation of Weak face simultaneously softens, and shearing strength is gradually reduced, and Weak face failure by shear locally occurs and produces shear crack, rain
Water, which constantly enters these cracks, makes its full water, and pore water pressure increases to form excess pore water pressure, and shear crack gradually extends company
Logical to form shear surface, weak surface intensity further reduces, and ultimately results in the local soil body because shear surface shearing strength is less than shear stress
And glided along slip band;The presence of intermediate recess landform makes whole potential slip mass be in concave slope landform, and slip mass surface is more sharp
In collecting more rainwater, beneficial to slip mass unstability.Free face is usually that slip mass cuts outlet port, and rain penetration enters the soil body
Along slope after lower formation shear surface, it is more easy to penetrate at free face to ooze out, and then cause slopes to glide.Therefore the gradient, upside are steep
Slope, intermediate recess landform, free face landform etc. can all play a role in landslide, but slip mass gradient α influence is maximum.
Slip mass gradient α, upper steep terrain factor U and both sides multi-stress C are fully incorporated in together by formula 3, synthetically consider ground
The effect of shape factor, embody each factor of influence correlation and importance.
