Abstract:
1. A method of generating an alarm indicating movement of a slope under inspection, said method including the steps of: (i) setting at least three stability set points including a first set point, a second set point and a third set point; (ii) determining a first change between the first set point and the second set point; (iii) determining a second change between the second set point and the third set point; (iv) determining a change ratio of the second change over the first change; (v) determining a first time taken for a slope to exhibit change between the first set point and the second set point; (vi) determining a second time taken for a slope to exhibit change between the second set point and the third set point; (vii) determining a time ratio of the second time over the first time; and (viii) setting an alarm if the time ratio is less than the change ratio.
