Abstract:Analyzing the effect of precipitation on data observed by horizontal pendulum tiltmeters at Yunxian station, we found: in spring and winter, as it accumulatively comes to 15 mm, precipitation effects ground tilt amount; in summer and autumn, when the cumulative value of rainfall reaches the driving rainfall,there is a good correlation between rainfall and slope. In the middle of the rainy season, the relationship is not obvious.Due to the vertical pendulum observation curve, there is strong correlation between rainfall accumulation and the value curve.We use the unary linear regression method to rule out of rainfall interference.
