The lattice shaped diaphragm wall is a kind of new revetment structure,which has high rigidity.The structure can be safe and environment-friendly with the help of soil reinforcement in front of revetment to reduce the horizontal displacement of the lattice shaped diaphragm wall.The paper introduces the application of the lattice shaped diaphragm wall revetment based on an engineering project of the water intake in an electricity plant.A 3D model is established by software Plaxis3D and soils are constituted by HS model.The design method of soil reinforcement is given to analyze the influence of the replacement rate,width and depth on the horizontal displacement.Since the revetment in soft clay is sensitive to the soil strength indicators,the sensitivity analysis is carried out.
