IMPROVED GABION TECHNOLOGY FOR SOIL STABILITY AND FLOOD CONTROL IN NEPAL

Abstract
Abstract - Gabions are essentially wire mesh baskets or containers that are filled with earth or stones, which are used in building structures such as dams or dikes. In developing countries, gabions are sued for river bank protection, erosion control, slope stabilization, road side stabilization and different infrastructure development. The present problems in gabion system in Nepal is less durable and unstable. In order to analyze the effectiveness of the gabion technology in Nepal. This study investigated on-site the prevailing gabion technology in Nepal and Japan for river bank protection. In the field, both traditional Nepalese construction methods and Japanese techniques, which is superior in stability, were applied, and the post-construction deformations were compared based on local field survey results and other data. In addition, a new method that is easy to construct, economical, and suitable was constructed on site. Geo-technical and hydrological condition of the soil were analyzed for ground condition. The Japanese, Nepali and improved i e; Japanese and Nepalese mix, gabion technologies are analyzed on the basis of different parameters such as; design and planning, ease of construction, material availability, adaptability of construction, cost of construction, durability and stability. As far as comparisons are concerned, the results of the short-term survey, the frame of gabion cage constructed using the traditional Nepalese technique was deformed by the overburden pressure. The developed method deformed more than the Japanese method, but withstood the action of external forces from the river and earth pressure. An improved gabion technology was developed from the series of ground survey, designs, and discussions with expert team from Nepal and Japan engineers. It is inferred that the improved gabion technology is effective for riverbank protection in developing countries with small budgets for construction of structures.
