     Real-time monitoring system about surface and deep displacement of landslide is the relative displace- ment measurement instrument. On the basis of field investigation, the geologic environment and characters of Sheng- li landslide are studied in detail in this paper. Geologic origin and the environment origin are examined. The geolog- ical structure type（ sand＋clay＋sandy mudstone） is the crucial factor. Continuing excavation, exploding and applied loading are the influencing factors. The high intense and large rainfall is the triggering factor. By analyzing surface and deep displacement monitoring data, the rate of surface displacement is l mm＇d-1 three months before the rain- storm, at the stage of uniform creep stage. It appears traction landslide characteristics. At the same time, the deep displacement remains unchanged. After the rainstorm, both surface and deep displacements increase suddenly. Three deep displacement monitoring points with different depths effectively capture the approximate locations of the slip surface and dislocation distance, which can provide reference for determining the depth of deep displacement monitoring.
