Abstract: | Based on the construction of Ning-An passenger special line and Qing-Yanrong passenger special line, the mechanical properties of PC box beam are analyzed and researched during construc- tion, combining with the construction equipment. It deeply analyzes the strength factor, the anti- crack safety coefficient, stress distribution, steel stress and concrete crack, etc. It provides the expe- rience as a reference for the similar engineering project. |
