Inverse-square-root-acceleration method for predicting the failure time of landslides

Predicting the failure time of unstable slopes is one of the most pivotal issues. In this paper, the inverse square root acceleration (INSRA) method was proposed to estimate the time-of-failure (TOF) of landslides.

Description
Summary:Predicting the failure time of unstable slopes is one of the most pivotal issues. In this paper, the inverse square root acceleration (INSRA) method was proposed to estimate the time-of-failure (TOF) of landslides. Four collapsed slopes were presented in the three open-pit mines, two of them were probed by ground-based radar, and two of them were obtained from previous scientific papers. The inverse velocity (INV) method and INSRA method were adopted to analyze these four landslides and one slope which had great deformation but did not reach failure. Compared with the traditional INV method, the INSRA method can promote the forecasting effectiveness and has the advantage of higher accuracy.
