Mountainous region accounts for the 67% of national territorial area.Therefore China is both frost zone big country and mountainous region big country.This is objectively determined
A large amount of frost zone side slopes are emerged in the engineering constructions such as China traffic route, water conservancy.In addition, current city earth polar for building
To be in short supply, many engineering constructions require excavation pit, and are influenced by on-stream time and speed of application, inevitably there is base pit engineering
It needs to undergo winter and spring.Nowadays it is Shotcrete Rockbolt Support Technique that the support engineerings such as side slope and foundation pit, which are applied most common,.A large amount of work
Journey practice have shown that, frozen ground regions build side slope and foundation pit, experience winter frost heave spring melt and caused by engineering
Accident is innumerable.
With the rapid development of economic construction, miscellaneous cold regions engineering is built in succession, and engineering construction produces largely
New side slope.The appearance of new side slope, inevitably destroys original surface vegetation, flow path etc., causes earth's surface heat transfer boundary condition
Change, the endotherm area and caloric receptivity in slight slope face dramatically increase after the completion of construction, and the heat balance of original frozen soil is destroyed, always
Body heat content sucking is greater than heat and pays, and freeze thawing thermal properties increase, and frozen soil upper limit decline influences the stability of frozen soil side slope,
And frozen soil side slope stability has potential threaten to route long-term safety operation.Therefore, it is necessary to carry out engineering control to it.
Common control measures are to change to fill out freeze thawing layer soil body, and slope surface adds insulating and the bolt-spary supports in the area Fei Han is arranged
It applies, due to frozen soil ice content height and temperature sensitivity feature, and warming with global climate, the heat amount of melting increase, cushion
Project amount is huge, and heat-insulation and heat-preservation fixing measure is unreliable, and influence surface vegetation cultivated area, desertification degree gradually gradually on
It rises, common shotcrete supporting construction cannot reduce the decline of frozen soil upper limit, and be easily destroyed by strong frost heave supporting construction.
