    • In Japan for protecting the slides of steep sloped areas, covering the face of slopes by sprayed mortar became popular since 1970s. For monitoring the physical condition of these walls Thermal Infrared Imaging Method is used as one of the techniques. But, these monitoring investigations are performed mainly in the daytime and led to some problems in the judgment. This study aims to find and eliminate those problems and misconceptions by conducting the investigation at night. Accordingly, from the results of field investigation and Finite Element Method (FEM) mathematical analysis, this study confirmed that, nighttime investigation of the mortal wall reduces some of the problem factors evident at daytime.
