Description
Technical field
The present invention relates to debris flow control works technical field more particularly to a kind of earthquake region breaking mud flow flows
Calculation method and application.
Background technique
Mud-rock flow is the extremely complex geological disaster occurred in Mountainous Regions, it is by the solid matters such as soil, stone and water
Mix the two-phase fluid moved under the effect of gravity along steep ditch slope.China's mud-stone flow disaster spreads the vast mountain of 26 provinces and cities
Area is to be threatened one of the countries with the most serious ... by mud-stone flow disaster in the world in total there are about tens of thousands of distributions.Mud-rock flow is along nature
The mixture of the loose earth and water, gas of slope surface or the flowing of pressure slope, Chang Fasheng are a kind of comprising a large amount of mud in small watershed in mountain
The solid, liquid, gas three-phase fluid of sandstone block and boulder is in the motion states such as stickiness laminar flow or dilute property turbulent flow.Mud-stone flow disaster night hair
Rate is high, it is sudden it is strong, the oncoming force is swift and violent, harm extensively, hazard approach has silt to bury, washes away, hitting, blocking, crossfire changes its course, burst,
It abrasion, Blaps femaralis and climbs, squeeze main stem etc..Wherein, breaking mud flow is when channel blockage body bursts due to bursting
Flow amplification effect often makes the harm of breaking mud flow much larger than general mud-rock flow.It bursts to utmostly reduce to the greatest extent
Certainly type mud-stone flow disaster bring is lost, it is necessary to which Flow amplification effect of bursting to it is studied.
Southwestern China area is distributed in front of Wenchuan earthquake is mostly ice-lake breach type mud-rock flow, has broken this after Wenchuan earthquake
One layout.The geological disaster induced after shake is formed by large-scale natural blockage body, easily bursts under heavy rainfall effect and excites shape
Huge on a large scale, the high breaking mud flow of harm, therefore, the research to the breaking mud flow of Wenchuan earthquake region be very it is necessary to
's.The research of flow calculation model is carried out to breaking mud flow typical in the earthquake region of Wenchuan, research achievement can be Wenchuan earthquake region
The work of preventing and reducing natural disasters such as risk assessment, the detection early warning of breaking mud flow provide foundation.Use grain composition, mud now both at home and abroad
The indexs such as rock glacier bulk density, the resistance of motion, flow velocity, flow describe debris flow feature, and flow or flow velocity, mud-rock flow bulk density
It is three mostly important indexs with impact force.Mud-rock flow bulk density is the most basic physical index of mud-rock flow, it can not only reflect
The genetic type of mud-rock flow also determines all various aspects of debris flow feature.And the flow of mud-rock flow depends on basin and exists
Production remittance process under different geological conditions, calculation method can substantially be divided into form investigation method, method of completing the square and factor diagnostic method.
Calculating for breaking mud flow flow is simultaneously not perfect, but for its huge harmfulness, conducts further research to it
It is necessary.
Publication No. CN 108984962A, publication date discloses for the Chinese patent literature on December 11st, 2018 bursts

Certainly type viscous debris flow impacts for lower bulky grain damming dam breaking method of calculating flux, has higher applicability；It calculates public
Formula is simple, and parameter needed for calculating is few, and parameter is easily obtained；It can be suitable for when lacking a large amount of surveys early period
Earthquake region breaking mud flow flow rate calculation.
Due to damming dam downstream material resource situation variation compare with will not be to dam breach position section peak flow for blockage body
It causes mutation to influence, is modified so introducing silt adjusted coefficient K s, helps to improve the accuracy of calculated result.
In step a, it is made of according to a mud-rock flow process total amount clear water flow and the mud-rock flow amount of going out, has obtained mud
The rock glacier amount of going out；Similarly, in stepb, consider the energy system on natural damming dam in catchment basin of debris flow after shaking, definition is burst
Energy when mechanical energy possessed by each section subsystem is not lost by fricting movement before type mud-rock flow fluid is formed is the type that bursts
The initial potential energy of mud-rock flow, i.e. debris flow body potential energy, which are equal to upper water body posture, to obtain crevasse the sum of with mud-rock flow material resource potential energy
The section peak flow at place；In step c, law of conservation of energy is introduced, glacial-lake burst debris flow kinetic energy subtracts that move to downstream disconnected
The energy of area loss is equal to the initial kinetic energy of this section part, so the peak flow for obtaining crevasse downstream section calculates public affairs
Formula；Parameter needed for entire calculating is few, calculates simple.
Below with reference to specific example, detailed description of embodiments of the present invention:
Seven Pan Gou are located at the Wenchuan County west of a city south town the about 5km Chu Weizhou village Qi Pangou, whole topography east southeast in seven disk Watersheds
