The present invention is achieved through the following technical solutions:
The EARLY RECOGNITION method of ice water mud-rock flow, which comprises the following steps:
A, by Google Earth or in-site measurement, determine the basic terrain data of ice water mud-rock flow: glacier and accumulated snow area with
The ditch bed gradient α in formation area more than lower accumulation area；
B, the ditch bed gradient α in formation the area more than following accumulation area in the glacier to different gradient section and accumulated snow area is carried out respectively
Measurement, using channel length >=10m as canonical measure fall of channel；
C, by the ditch bed gradient α for forming the area more than following accumulation area in glacier and accumulated snow area to the ice water of different gradient section
Mud-rock flow carries out EARLY RECOGNITION:

Ice water mud-rock flow EARLY RECOGNITION in 45 °.
Formation area, that is, basin middle and lower reaches channel more than following accumulation area in glacier of the present invention and accumulated snow area.
Basic principle of the invention is as follows:
The formation mechenism of ice water mud-rock flow is the raising due to temperature, causes the upstream ice dissolution of catchment basin of debris flow, is risen
The bulk solids material resource of dynamic middle and lower reaches, forms mud-rock flow.Therefore the formation mechenism of this kind of mud-rock flow and western China are universal
Ditch bed start type mud-rock flow it is different, it is also different from the shallow failure integrated type mud-rock flow in east China area.Ditch bed start type
Mud-rock flow is the big flow torrential flood erosion ditch bed bulk solids material resource formed due to heavy rainfall, forms mud-rock flow.Shallow failure converges
Collection type mud-rock flow is that first have more shallow failure to enter channel due to the rainfall of long period and compared with heavy rainfall and form mud-rock flow
Material resource, then carried by larger flow flood, form mud-rock flow.The mud-rock flow of both types requires stronger rainfall intensity shape
At larger flow flood, corrodes and carry ditch bed solid material resource.But since temperature raises caused by upstream ice dissolution formed
Often the duration is longer for river basin flood, but flow is smaller, is difficult as western general mud-rock flow, directly by pluvial erosion
It carries channel solid material resource and forms mud-rock flow.In China, the scene of ice water mud-rock flow is based on Tibet, Xinjiang, these areas
Catchment basin of debris flow fall of channel it is larger.The formation mechenism of ice water mud-rock flow are as follows: the river basin flood that upstream ice dissolution is formed
The local water level lifting in channel causes local bulk solids material resource to satisfy water unstability, and cause unstability when water level lifting is higher
Region upstream corrodes, and downstream is washed away, and eventually forms mud-rock flow.Bulk solids material resource satisfies the gradient required for water unstability much smaller than pine
The angle of repose of scattered seed.Therefore fall of channel is too small, cannot reach minimum grade required for the full water unstability of bulk solids material resource,
Ice water mud-rock flow is difficult to occur.If the gradient is excessive, the flood flowing that upstream ice dissolution is formed is too fast, and water level is difficult to be lifted,
Also it is hardly formed mud-rock flow.
The present invention by the development and distribution characteristics of mud-rock flow along comparative study Tibet and Natural Division for Highway in Xinjiang Uygur Autonomous Region, research obtain with
Ice water catchment basin of debris flow middle and lower reaches fall of channel is the ice water mud-rock flow EARLY RECOGNITION method of foundation.The present invention is from ice water mud-rock flow
