During the excavation and reinforcement of a cataclastic rock slope as highway construction in a mountain area, a dynamic monitoring system was used to measure its stability. Field data collected showed that, in normal conditions, the stress field of the slope body was influenced mainly by ambient temperature, and the influence range is limited. During construction, even the stretching of the anchorage cable disturbed the stress field of the slope body, the disturbance just maintained in a relatively short time. Combining with data from deep-seated displacement monitoring, it could be concluded that, as construction, the stability of the slope was influenced by the following factors: 1) artificial activities: excavation, blast and support; 2) natural disturbances: rainfall, etc, but the integral body of the slope was stable.
