frost heave造句
1) As to the phenomenon of secondary frost heave, the behavior of water flux in frozen fringe is one of the major subjects to study.
2) Quasi coupling numeric analysis of frost heave effect of horizontal freezing in artificial ground is suggested.
3) Especially in the processes of frost heave and formation of ice, the function of stress is greatly important.
4) The normal frost heave force is an integral of soil frost heave stress at the freezing front along the range effected by a foundation.
5) Horizontal freezing induces ground frost heave and ground displacement. Excessive uneven displacement or deformation may damage the surrounding building.
6) This paper introduces the road frost heave damage causes and prevention and control measures.
7) The frost heave and thawing settlement of frozen soil area can do great harm to the road and building which lies on it, such as the crack, settlement, fragile structures foundation element etc.
8) It is found that the frost heave curve has a good self-similarity, and the fractal theory can be used to describe the frost heave curve.
9) It is the vertical migration that causes strong frost heave in the upper subgrade.
10) Because of the cold weather in the winter in the northern areas, the lining channels often be damaged by the frost heave.
11) This paper introduces cause and prevention measure of road frost heave in frozen earth area.
12) The freeze-thaw history of soil is important to assess and predict frost heave. Different freezing modes will lead to redistributions of water and salt and variety of dry density.

14) The numerical analysis is performed by using ABAQUS, and considers temperature boundary conditions, thermal property parameter of soil layer, frost heave model parameter.
15) Those effects can result in dam cracks, cracks under construction enlarged and dam surface destroyed by freeze-thaw, deep concrete destroyed by frost heave.
16) The driving force of moisture migration in soil is the key of discussing the mechanism of freezing ice and frost heave and the stress of freezing soil.
17) As for present technology, there is certain hazard, especially frost heave, so that the test study on soil is extremely significant, under different artificial ground freezing conditions.
18) Regarding on research background of the crossing engineering in Shanghai stadium, the express of frost heave for multi-freeze pipes is derived by the basic principle of superposition method.
19) The analysis result shows that the ground deformation due to the frost heave is within the permissible limit of ground displacement.
20) In this paper, the analyses on influencing factor of frost heave are being conducted in the light of seasonal frost soils for highway projects.
21) The key technology of subgrade design is solving the problem of subgrade frost heave in seasonal frozen soil area.
