This paper introduces some resarch results on sediment model experiment of navigation in the course of construction.

Study on operational mode of TGP lock and navigation conditions during cofferdam retaining water;

Research on navigation conditions downstream TGP during its flood-discharge;

Research on navigation condition and the configuration of diversion channal of Caojie hydro-junction in Jialing river

Study on navigable condition in the intermediate channel between the two ship lifts of Longtan Power Station;

From the results of model tests, width of the entrance,structural pattern of the breakwater and the relation between water depth and navigable conditions at the entrance are described and the main factors influencing navigable conditions at the entrance is analyzed.

So it must further demonstrate navigable condition of the key lock by ship model testing,and verify the reliability of navigable condition in the key lock.

Study on construction period navigation conditions to Changshou Railroad Bridge of the Yangtzi River;

Based on the physical model and model-ship test, this paper studies the navigation conditions of Naji Waterway when arranged at left and right banks, and engineering measures for improving the navigation conditions.

Through model test, this paper analyzed the influence of non-steady current produced by the Three Gorges Power Station at the time of flood discharge and daily regulation on the navigation conditions of the reach between the Two Dams.

Simulation of thermal stress of Longtan RCCD based on construction conditions

The fabrication of unit of grid is mainly introduced as well as construction method of accumulative slip with multi-support points,which resolve the installation questions of grid structure under limited construction conditions.

The design and construction conditions of the general bulk cargo berth of Dalianwan Bay in Dalian Port,as well as the optimal selection of design proposals and comparison of the construction cost are described.
