| Abstract: |
| 【Objective】The soil in the seasonal frozen soil area freezes when the temperature drops in winter and melts when the temperature rises in spring. Water migration is the root cause of frost heaving of soil, which seriously endangers the safety and service life of engineering structures such as canals, highways, railways, bridges, etc. In order to reduce the problem of freezing damage to engineering structures, the problem of water migration in frozen soil is studied. 【Method】Based on the basic concepts, phenomena, test methods, change laws and influencing factors of water migration, the domestic and foreign researches on water migration during soil freezing and thawing are summarized and summarized.【Result】The problems and deficiencies in the current research are summarized, and the research directions of water migration in the frozen soil area in the future season are prospected.【Conclusion】At present, scholars have made great achievements in the study of water migration, but there are still some problems, such as the incomplete impact of natural conditions when carrying out water migration experiments, the parameter determination method is not accurate enough when establishing coupling models, and The migration influencing factors are considered in a single factor in the test, which cannot fully reveal the mechanism of water migration. |
