Abstract: With the development of bridge construction to the mountainous area and the increased difficulty of construction, the problem of bridge geological hazard is becoming more and more significant. In this paper, a project example was used to study the variable displacement monitoring technology of bridge under the influence of landslide geological hazard, and a scientific and rational monitoring scheme was made, and the regression analysis method was used to analyze the bridge displacement comprehensively, and the effect was good. The monitoring data could provide the basis for the bridge safety assessment and decision under the landslide disaster. For the same kind of bridge reference.
