Construction technology for deep channel section of upstream separation levee of TGP;

Analysis of separation levee settlement of upstream navigation channel of TGP s temporary shiplock;

The flow field requirement of Chinese sturgeon spawning, characteristics of flow field under different discharge conditions,and negative effect of separation levee on the whole spawn.

At last,the deformation regularity of the separation levee is summarized.

The downstream navigation channel of the Three Gorges Project is excavated on dry land,which requires that the partition dikes should prevent leakage.

Based on laboratory test of weathering sand taken from the partition dikes of lower approach channel of the Three Gorges Project ,the physical and mechanical characters of weathering sand are analyzed and appraised.
