The profound researches on the mechanism of photooxidation, rheological properties, service performance and retained fatigue life of asphalt binder, under the condition .

Through the example of Ganjiang Bridge on Jing-jiu railway line, the fracture mechanics model applied to evaluate the remaining fatigue life of existing riveted railway br.

This paper establishes the fatigue stress spectrum of the transom and the bottom chord of a bridge over the Yellow River based on the measured stress and confirms the residual fatigue life by using mathematical model of existed steel bridge fatigue life .

To determine the overhaul period of the equipments and prevent accident, it is necessary to predict the serving gear residual fatigue life.

According to its own feature of marine drilling riser, by using the single adaptability evaluation method based on breaking mechanics and considering the fatigue load feature of riser and random load effect of sea wave, the drawbacks is analyzed and controlled to prevent fatigue failure and the residual fatigue life is predicted.
