| 摘 要： | 采用ANSYS软件和圣维南原理对永定新河特大桥的0号块顶板、底板、腹板和横隔板的空间应力进行分析。通过分析,获得了0号块准确的应力分布规律:以压应力为主,局部出现拉应力,虽不大,但已超出混凝土抗拉设计强度。

| Abstract: | There was a space stress analysis by ANSYS and Saint-Venant's principle for Yongding New River extra-large bridge including its zero block roof, bottom, web and diaphragm. The accurate stress distribution rule of zero block was gained by the analysis, which was dominated with compressive stress and tensile stress appeared partly. Meanwhile, the tensile stress was not large but over the concrete tensile design strength. |
