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