| Abstract: | Based on the example of NO.54 pier excavation of the continuous beam section of the extra-large bridge across the Shahe River on the Jin-Qin railway line,a mechanical calculation and reinforcement and slide checking of supporting piles have been carried out.Practice showed that the program was convenient and practical,and could effectively protect the existing circuit-based security. |
