Groove construction is the first procedure in water supply engineering.An optimal construction technology could ensure the safety of groove and then guarantee the construction safety and quality.Here,several groove construction technologies are discussed combined with the engineering conditions of Changxing Island＇s strait section,and a lot of numerical experiments are done to optimize the construction plan,such that it could fit the construction section.A best construction technology is finally put forward,and the numerical simulation is used to analyze and optimize the cofferdam width and gradient ratio,and the result is very helpful.It is proved by the site operation that the plan is feasible,it could not only ensure the construction duration,but also save the cost of project.All these as mentioned above could be consulted by similar engineering projects for construction and design.
