| Abstract: | The article mainly introduces the basic concept and design principle of pre-pressed double tensile-press action pre-stressed concrete simple-supported beam and its construction technique in the application of the practical project (Huachen Middle Road Youdun Harbor Bridge Project). Compared with the same simple-supported beam bridge, it has the brilliance characteristics of strong spanning capability, legerity, beauty and saving the integral engineering construction cost, which is worth to popularize. |
