Project Freeze Injury Question Research

The project freeze injury question, exists generally in cold and the cold area. It to the project the harm is quite big, in particular hydraulic engineering, because its near water environment reason, the freeze injury question is more prominent. Ices up the harm because because because in this the water which the volume expansion causes, the disarrangement of the structure which the building adjacent formation medium heave distortion causes, the freeze function causes the load to change the component which causes (thing) the stress strain change and so on, has the extremely broad cloth and the sensitivity. This question has already aroused internationally, the domestic many scholar's strong research interest, also has made some varying degree research progress and the achievement. Looked from the present these research progress and the achievement, but also only is in initial, in the foundation periphery research, fundamentally or from can solve the project actual problem to need to come to look also appears insufficiently many, insufficiently deep, theoretically qualitative, the quota research results are not also many. The project actual and in the production also has many pending issue to need to study.Hydraulic engineering actually already extremely urgent request solution project freeze injury question, also very realistically proposed this aspect research duty and the topic for the water conservation scientific and technical worker.This article author unifies the project actual problem, divides the type mechanism research obtaining which destroys by the heave, the research ice zhang development as well as the change rule, research frozen earth physics, mechanics character and the soil body moisture content moves frozen the mechanism, and stressed the canal lining body heave question research in the article, to the adfreezing force, the frost heaving pressure has made the more thorough theoretical analysis, has established mechanics computation model separately. Using this model, can easy, in the quota computation project diversity position frost heaving pressure value, again adopts according to the frost heaving pressure size correspondingly pushes the anti-processing measure. Moves frozen in the moisture content in the fundamental research foundation, proposed the reduction measure, namely the basis hole principle of detailed balance,...
