In recent years, the construction space of some cities in mountainous areas has been expanded by high fill projects, and the change of groundwater level after filling has attracted much attention. On the basis of a high fill project in Shaanxi, the groundwater level and the change of water content of soils in filling site are monitored continuously. The monitoring results show that the rise of the groundwater level at the lower reaches of the main channel after filling is obviously larger than that of the minor channel, and the maximum value is about 1.3 m. At the downstream position of the main channel, the water content of the deep fill increases with the depth. The measures for the main groove of loess gully high embankment in the groundwater drainage should be further strengthened to prevent the rise of groundwater level, and the construction at the downstream position of the main channel should be cautious considering the adverse effects of the increasing rate of water content of deep soils.
