Study of Prediction Control System for Construction of Bridges with Long Spans

To ensure all segments under construction to approach corresponding construction segmental reasonable states in both configuration and mechanics states and good behavior of structure after completion,escaping from all kinds of accidents in whole process of construction with high efficiency,safety,excellent quality of engineering achieved,the grey prediction model NGM(1,1) was proposed to fit prediction of any raw grey series by studying grey causes and whitening results based on the normalized mapping rules;random perturbation method of genetic algorithms was proposed to raise efficiency of forward rolling optimization;simultaneous analysis of strength and stability was carried out to ensure safety of strength and stability.Based on these,the construction control system with its theory characteristics was expounded and its application was demonstrated by a practical example.
