Research & Development for the Digital Simulation Software of 3D Terrain in Dredging Project;

At present Taihu lake is confronted with serious eutrophication problem, The ecological dredging project of Taihu lake contaminated sediments has already started, but experts have different viewpoints about the problem of Taihu lake desilting.

The auto linking method of plane triangle net producing is used in producing plane triangle net of waterway measure points in development of waterway dredging project design system,but there are two shortcomings.

Long range relay to transport technological measure on Chaohu bottom mud dredging engineering;

In implementing dredging engineering, real－ time construction period prediction was usually carried out according to the related data obtained successively, which was taken as a basis for adjusting the construction force and construction method.

In dredging engineering,the work of calculation of cutting is burdensome .

Construction management for dredging works;

Based on the introduction of the application of IT technology in dredging works and the analysis of the increase of dredging accuracy and its benefits with the application, we get the conclusion that IT technology could be applied much in traditional dredging field.

In order to thoroughly overcome ravages of a constantly escalating drought, it is a important measure to augment groundwater by reverse dredge theory and reverse dredge engineering, traditional engineering join force with reverse dredge engineering, safely regulate water resource in land spatial field and let land have sufficient water resource in every season.
