And collision incidents between the ship and the bridge happen occasionally around the world, which has become an important issue in the design and maintenance process of channel bridge engineering [1].
If consider the details of vessel collision strictly, engineers may can't finish this design, only if they do a special study[8].

After many years analysis and research, we found that the main factors that generally influence the fluvial process of wandering channel are water and sediment conditions and boundary conditions of riverbed (including boundary conditions of engineering).
But the swing of the main flow also great in the reach with less engineering control, abnormal meander increased and the phenomena that the engineering can not control the main flow is serious, the river banks that in front of the engineering were seriously collapse.
They mainly show in the following aspects: The stability degree of river regime is related to engineering arrangement, engineering density and meander parameters; Curving projects are beneficial to control river regime; The river regulation works control the swing of mainstream.

One of the points of analysis in this study was to seek for a view of Production Engineering in all the ways that the steel with reduced thickness is involved, from its production, with development cost analysis to the final product with its market analysis.
“Once known such properties for various alloys, the project engineer can select, depending on the application in sight, the most appropriate material.”
Some of the consumer segments of flat steel are: automotive industries, domestic utilities, packaging and civil construction.
The increasingly demanding and competitive steel market asks industries and engineers to develop new ways of working with the steel, since its chemical properties allow several practical applications.
