Assessment of the Stability of Slope in Navamindakasatriyadhiraj Royal Air Force Academy at Muak lek District, Saraburi Province

Abstract

During the construction of Navamindakasatriyadhiraj Royal Air Force Academy at Muak lek District, Saraburi Province, a number of slopes were built in order to adjust the grade of construction site. The failure of the slopes may cause severe damage to the properties and people who are using the buildings. This research aims to investigate the possible factors that can be a cause of failure of the slopes and to analyze the slope stability in this area. The prevention techniques for the slope failure were also proposed in this research. The slope close to the Air Cadet King’s Guard Regiment Headquarters was selected and used in the evaluation. The soil samples obtained from the construction site were tested to determine their properties which used in the process of slope stability analysis. The method of slides was used in the analysis and the results showed that the factor of safety (FS) on the critical plan of the slope was 4.1 which is higher than the minimum requirement of FS of 1.2. Therefore, it can be concluded that the slope is stable under the condition that only soil weight was considered.
