The traditional calculating method for blocks reaction during ship docking is discussedand its drawbacks,such as the limited range of application and incompleteness of calculatedresults,are pointed out;The Finite Element Method is used and compared with the tradi-tional one.

Integral non-linear stability analysis and safety evaluation for high gravity pier-arch dam at Sizhai Reservoir;

Application of flaring gate pier and baffle block at Banduo hydropower station;

Effect of baffle block on hydraulic jump length is considered by changing baffle block position .

By using joint energy dissipation of wide flange pier and plunge pool,and layout of baffle block on the apron,the efficiency of energy dissipation for hydraulic characteristics of three-dimensional flow can be increased.

The structural stability and safety grade of the components including earth dam,arch dam,gravity dam,and gravity abutments are evaluated to provide the necessary data for the management and regulation of the project.

In order to evaluate the dam safety of Tanzikou reservoir,the arch dam and its gravity abutments on the left and right sides of the reservoir have been studied to ascertain the defects and the main reasons causing the defects.

As the limitation of topography and geologic structure defect of left bank,and for the purpose of eliminating the influence of arch thrust on the vertical shiplift and gate bay,gravity abutments (No.
