Report Title : Trial Application of Thermal Infra-red Image and Seismic Sympathetic Vibration Techniques for Slope Investigation (2007), 52 p.

Author : T.H.H. Hui & H.W. Sun

Abstract

This report documents the details and findings of some pilot field trials of two non-invasive techniques, namely, Thermal Infra-red Image Analysis (TIIA) and Seismic Sympathetic Vibration Analysis (SSVA), for the detection of voids between a hard surface cover and the underlying slope-forming material. The trials were carried out at three separate slopes in Hong Kong. The principal objective of the field trails was to assess the applicability of TIIA and SSVA to landslide investigation or slope investigation work.
