| Abstract: | Skew bridge pier and abutment adopt parallel's axis layout,in order to describe the easement curve and straight line intersection point's mileage.This paper describes Newton-Raphson method to solve this problem,approaching number of times is not too much,and the required precision is very good.The results show that its one of good methods to describe the easement curve and straight line intersection point's mileage of the skew curved and ramp bridge. |
