摘要：

An application of high-resolution tilt meter technologies is presented to make clear the practicality of it, as a diagnostic tool available for a rapid assessment of limestone slope stability. Focusing to limestone-cover slopes in quarrying, the characteristics of tilt-time records are analyzed from both of macroscopic and microscopic viewpoints, and the tilt velocity analysis is proposed to evaluate the slope stability. The shear fracture propagation on the boundary between cover limestone and behind weak-measure is discussed from the time dependency of tilt velocity, which is significantly affected by rainfalls. Further applications of high-resolution tilt meter technologies are discussed along with the possibilities of high-resolution technologies in near future.
