摘要
In this paper, the statistical diagram of landslides in days is gained by analyzing the data of a certain number of slides. Further efforts is made on the deduction of the formulas of tidal stress at surface of the Earth, by modifying a simplified elastic earth model based on the earth tide theory. The results show that the tidal stress and the factor of slope stability change with time at daily period. Therefore, the characteristic with daily successive variation of landslides and the mechanism triggered by earth tide are elaborated quantitatively.
