Description	Journal: Iop Conference Series: Earth and Environmental Science The change of water content of expansive soil in canal slope is very unfavorable to the stability of the slope. In order to analyze the influencing factors and laws of water cut, the relationship between water content and voltage of expansive soil, the relationship between initial water content and expansion force, initial water content and disintegration of expansive soil were tested relationship. The gray correlation model was analyzed based on the vertical displacement, water content, suction, rainfall, soil temperature and temperature data collected on the site. It is preliminarily believed that the main influencing factors of the change of water content of expansive soil in the test section are temperature, rainfall, evaporation and suction. The mechanism analysis of the grey relational model is also obtained: due to the lag of the rainfall infiltration process, the atmospheric rainfall can only penetrate into the 1.6m deep strong expansive soil after 3d, and the influence depth is less than 6.1m. The research on the influencing factors of the change of water content of expansive soil provides the basis for the development of prevention and control measures for canal slope soil in the middle route of South-to-North Moisture Diversion Project and the safe management of channel operation.
