| Abstract: | Taking Ningbo Airport Road – North Outer Ring Grade Separation Project as the background,the article introduces and studies the multi-span 20-m pre-tensioned pre-stressed hollow slab beam and the main longitudinal beam simple-supported post-cast-in-site crossbeam to form the continuous system.Combined with the static load experiment of the completed bridge,the article verifies the rationality of calculation analysis,and also sets forth its application prospect in the bridge projects. |

| Keywords: | simple-supported post-continuous grade separation transverse distribution coefficient |
