Abstract:The construction of cofferdam is an important temporary project to create dry land construction conditions for levee engineering. In recent years, steel sheet pile cofferdam has been widely used because of its safety, reliability, strong adaptability, green environmental protection and other characteristics. However, the construction design of steel sheet pile cofferdam is still based on experience judgment, and the methods of engineering analogy and theoretical calculation are usually adopted. In view of the lack of standard for cofferdam construction in levee engineering in Shanghai，the main points of design and construction of steel sheet pile cofferdam are pointed out in this paper, based on the actual operation and management of levee in Shanghai. It is put forward in this paper of the application assumption of steel sheet pile cofferdam and temporary flood wall in combination with the actual levee engineering. This study provides an effective way for standardizing cofferdam design, shortening construction period, reducing construction cost and improving the level of fine management of levee engineering.
