| 空间预应力束引伸量的求解是桥梁施工控制中的重要环节,介绍了在CAD图形软件下,空间预应力束引伸量的求解过程,对单端张拉、双端对称张拉、双端不对称张拉以及斜腹板中预应力束引伸量的求解方法作了详细阐述. |
| 英文摘要: |
| Solution to spatial prestress tendons drawing amount is an important segment in bridge construction control. This paper introduces solution procedure of spatial prestress tendons drawing amount by CAD graphic software, and puts forwards the solution of prestress tendons drawing amount,including single-ended tensioning, double-end symmetric tensioning, double-end asymmetric tensioning, skew web plate and so on. |
