Design and Construction of Straw-bag-reinforced Mud Wall for Soil and Water Conservation in Red Soil Moutain and Hill of South China

Based on previous studies and practices,a new straw-bag-reinforced mud wall was designed for the soil and water conservation in Changting County,Fujian.The structure offered an improved overall stability and balanced internal stress over the conventional mud walls,according to the engineering model.From the lab experiment,the hove tendons limit and the relationship between the allowable stress and deformation were determined to establish the theoretical anchorage length for reinforcement and soil deformation occlusal.Potential problems encountered with and their countermeasures on the service life and construction of the newly designed mud wall were discussed.A blueprint for the construction and criteria of the straw-bag-reinforced mud wall are presented.
