Slope Stabilization and Erosion Control on Back Slope by Flapped Soi Bags and Soil Anchor in Kanchanaburi

Abstract

Kanchanaburi Province is located in the mountainous area with frequent erosion and slope instability problem, in particular, in rural road Kancahaburi no 3091 in Paag-Mhaung village of Thong Phaa Phum district. This paper presents the slope stabilization work along the back slope of this road, including flapped soil bags for erosion control with soil nail and screw pile for slope stabilization. Also presented are soil profile investigation using Kunzelstab penetration test (KPT), slope stability analysis and IoT field monitoring namely tiltmeter, soil moisture and rain gauge to evaluate the long term performance of the stabilization work.
