The testing purpose,model design principle,testing case,loading program,strain and arrangement of deformation test point of the special-shaped arch bridge test model are introduced in detail.

Testing purpose,model design principle,testing case,loading program,strain and deformation test point arrangement of the first Zhongshan Bridge test model are introduced in detail.

The paper introduce load programs and prestressing methods imposing on steel.

The necessity of making choices from loading and firming schemes of railway long heavy goods is discussed, and the method of making choices from many feasible schemes by using the theory of hierarchical analysis is also presented.

In the fury evaluation of air transportation loading plan,firstly,the index system of air transportation loading plan should be established,then,the weight based on AHP should be ascer- tained,and the subjection should be calculated by the fuzzy mathematic theory,Lastly,the example validates that the fuzzy evaluation method of air transportation loading plan is efficient.

The characteristics of the structure itself are utilized adequately in selected the unloading plan,the multi method of unloading was adopted,and the unloading status in the construction process was observed.
