| Abstract: | Alignment control is one of the key techniques of bridge construction with MSS, and pre-camber setting is very important in it.This paper analyzes the deflection character of bridge construction with MSS, and summarizes the pre- camber setting method of bridge construction with MSS based on pre-camber setting principle and method,which has been proved effectivly in the construction of approach bridge of Sutong Yangtze River.The method in this paper can be use for reference in the similar situation. |
