Preliminary investigation of subsurface properties by geophysical methods were carried out over the construction site of the 40 meters Thai National Radio Telescope (TNRT) facility planning by National Astronomical Research Institute of Thailand (NARIT) in the Huai Hong Khrai Royal Development Study Center, Doi Saket, Chiang Mai, Thailand. Multichannel analysis of surface waves (MASW) and electrical resistivity tomography (ERT) were utilized in mapping of Vs distribution to obtain information on ground stiffness and other supporting information on subsurface electrical resistivity, respectively. Results from data analysis showed that the topsoil was very dense with thickness irregularly varied from 5 meters to10 meters overlying the bedrock with high variation in stiffness caused by the different degrees of weathering. The information obtained led to the conclusion that the proposed TNRT facility construction site is in the category of site class B of which the ground stability is moderate and less vulnerable to earthquake damages. |
