DETECTION SUPPORT DEVICE FOR DEFORMED SPOT ASSOCIATED WITH LIQUEFACTION AND DETECTION SUPPORT PROGRAM FOR DEFORMED SPOT ASSOCIATED WITH LIQUEFACTION

摘要

PROBLEM TO BE SOLVED: To provide a detection support device for deformed spot associated with liquefaction and a detection support program for deformed spot associated with liquefaction, which can accurately estimate the positions of cavities generated underground due to liquefaction phenomenon.;SOLUTION: A measurement result acquisition section 40 acquires height information which is a measurement result obtained by a laser scanner, and a gradient calculation section 42 calculates the gradient of a ground surface on the basis of the height information acquired by the measurement result acquisition section 40. A recess detection section 44 detects, on the basis of the calculation result of the gradient calculation section 42, a recess that is formed by a planar bottom surface and a circumferential wall surrounding the circumference of the bottom surface and having a greater gradient than that of the bottom surface. A cavity estimation section 46 detects the recess detected by the recess detection section 44, having a shape peculiar to liquefaction phenomenon, and estimates presence of the cavities in the ground on the basis of the recess.;COPYRIGHT: (C)2013,JPO&INPIT
