Abstract
Soil slope failure is a common natural geological hazard in tropical countries, including Thailand. The general landscapes of Chaiyaphum Province consist of forests and mountains. Most of the areas are complex mountain ranges. Some roads, which run through hills, during rainfall often encounter slope failure issues that lead to significance and economic loss. The objectives of this research are to determine causes of slope failures by considering safety factor of slope stability based on case study of Highway 2159, Chaiyaphum - Huai Yang Dam section at Km 27+700, Chaiyaphum Province. The analysis was performed according to the Limit Equilibrium Method (LEM) and Finite Element Method (FEM) utilizing “Slide 2D” and “Plaxis 2D” computer program respectively. The results showed that safety factor of Limit Equilibrium Method was approximately 3.14 percent higher than the Finite Element Method, and the main factors which affect slope stability are water flowing down from the embankment onto the unprotected slope, causing erosion at the toe slope and gradually spread into the main structure and pavement layer. Reinforcement by Rock and Wire Mattress method was chosen as it increased stability, improved drainage efficiency along the slope, and reduced risk of erosion. In addition, Rock and Wire Mattress can be constructed easily and quickly as well as adopted in difficult construction sites and utilize construction materials and local workforces available in the area.
