The Method of Consolidating Double Curverd Arch Bridge by Shortening Span and its Application in Engineering |
| |
| Abstract: | A new method of consolidating double curved arch bridges is presented. By shorting the span, minishing the arch moment, the bearing capacity of the bridges can be obviously enhanced. The validity,economy and facility of the method can be identified by analyse and engineering applications. When the main purpose is to improve the bearing grade of the medium span bridges ,this method will be appreciated. |
