Optimization of Design and Construction Plan for Dock Conferrdam Built on Steep Bank

The conferrdam of the Dingheng dock project is located in the deep water of the steep bank of the Yangtze River. The foundation pit of the dock project, which is more than ten meters deep, may have negative effect on the safety and solidity of the eonferream. The paper studies and optimizes the design and construction of the conferream. The paper studies and optimizes the design and construction of the conferrdam and makes the most optimized construction plan according to the construction condition on the spot to get rid of all the factors which may threaten the safety of the conferrdam.
