Abstract

One of the main tasks in deformation monitoring is to investigate the movement or displacement that occurred to any structural object.The measuring techniques and the instruments used for such monitoring are categorized as geodetic and non-geodetic (i.e.,geotechnical/structural) methods.A monitoring survey has been conducted in a laboratory to detect the deformation of a light weight concrete block which undergoes load testing.A number of target points on one surface of the concrete block has been monitored by triangulation survey using a total station. Five epochs of measurement have been obtained and each epoch was based on the load applied ranging from 0kN up to 358kN.The investigation is supplemented by data obtained from non-geodetic instrument (i.e.,strain gauge).Results from such exercise indicate the practicality of the geodetic method in deformation detection for civil engineering application.
