| Abstract: | This paper describes forward analysis and backward analysis for simulating construction of continuous rigid frame bridge, and the application and process of gray prediction. The result of applying the introduced method to alignment control of continuous rigid frame bridge over canal on Shangtang extended road in Hangzhou is satisfactory. The connecting precision is ensured, but also the formed bridge alignment is matched with the target alignment. |
