Study on reliability and anti-deformation of bridge in mining subsidence area;

In traditional design method, differential settlement of subgrade is ignored, and pavement structure has little anti-deformation capacity.

On the basis of analysis on the influences of the foundation soil in goafs on the site seismic properties and the plane layout of buildings on the performances of the structural resistance to deformation,this paper puts forward a series of basic design plans and construction measures for buildings on goafs.

Results showed that high temperature resistance of deformation of 4Cr13 is not changed by adding copper and sulphur.

The curve of stress-strain of Q345 is found and then the resistance of deformation is obtained in different conditions when σ-(0.

A Dynamic Recovery Model for Flow Stress of Microalloyed Steel Produced by Compact Strip Production Process

On the basis of the data obtained from Cam Plastometer,an RBF neural network prediction model is established by Matlab neural network toolbox,which corresponds with the relationship between flow stress and chemistry elements,temperature,deformation strain and strain rate of carbon steel.

To improve the prediction accuracy of the flow stress,a hybrid model based on the Hybrid Least Squares Support Vector Machine(HLS-SVM) and Mathematical Models(MM) was proposed.

The compressing deformation with different temperature,rate and extent is executed to 20MnSiv steel on Gleeb-1500 thermal simulating test machine,its model of resistance to deformation in high-temperature rolling got,its continuous cooling transformation curve drew up with twin-pass compression method.

The resistance to deformation decreases with the rising temperature after 450℃.
