| Abstract | Landslide is one of natural disasters commonly happened in Thailand every year. On 23 August 2006, landslide was initiated in many areas of Nan province, northern Thailand after five days of the unusual heavy rainfalls. This event destroyed many houses, buildings and infrastructures. In this paper, we analyzed geological and engineering properties of residual soil derived from sedimentary rocks in this potential landslide zone, especially at Ban Nong Pla Village, Chiang Klang district. The properties of residual soil we analyzed included specific gravity, grain size distribution, liquid limit, plastic limit, plastic index, total unit weight and moisture content. Engineering properties included analysis in shear strength parameters were also carried out. As a result, the average moisture content in soil is of 24.83 %, the average specific gravity is 2.68, 44.93 % of the liquid limit, 29.35 % of plastic limit and 15.58 % of plastic index. Soils were classified using Unified Soil Classification System (USCS) as ML- CL, CL- ML, ML- OL, SC and SM. The cohesion of soil is between 0.096 - 1.196 ksc and angle of internal friction 11.51 - 35.78 degree, respectively. |
