Abstract
In view of the advantages of prestressed concrete(PC)continuous rigid frame aqueducts,such as su-perior mechanical performance,large span,and high bearing capacity,the(67+120+67)m continuous rigid frame aqueduct was laid out at the section of the Bid Ⅲ Sujiamiao Aqueduct of the Tingzikou Irrigation Area across the Zhangnan Expressway.This paper follows the specifications for the highway specifications and the hydraulic specifications to carry out the longitudinal checking calculation of the superstructure,and analyzes the checking results from the two aspects of the bearing capacity limit state and the normal service limit state re-spectively.The analysis results are as follows:the highway specifications are stricter than the hydraulic specifi-cations through checking calculation of the ultimate state of bearing capacity,while for the normal use limit state check,the hydraulic specifications are stricter than the highway specifications.Therefore,it is concluded that in the design of hydraulic structures such as continuous rigid frame aqueduct,it is necessary to comply with both the hydraulic specifications and the highway specifications requirements,and more importantly,it must first meet the hydraulic specifications,and then supplement according to the highway specifications.关键词
