Bridge cantilever pouring linear control construction method
The invention relates to a linear control construction method for bridge cantilever casting, which is used for carrying out linear control on axis, elevation and structural stress on a variable cross-section bridge adopting a hanging basket cantilever casting construction method, ensuring the reliability and safety of the structure in the construction process, and ensuring that the closure precision and the bridge floor line shape and internal force after the bridge is formed meet the design requirements. The method has the following advantages: 1, by combining the structure and construction characteristics of the bridge, the stress development condition is considered while the deflection of each control section and the transverse deviation of the axis are strictly controlled, and the actually measured stress value is ensured to be within a design allowable range; data support is provided for construction, elevation adjustment of the bottom formwork of the hanging basket is facilitated, the overall line shape of the variable-cross-section bridge is guaranteed, and closure precision is guaranteed; the construction quality is improved, the construction safety is guaranteed, the hanging basket construction progress is accelerated, and the construction period is shortened.
本发明涉及一种桥梁悬臂浇筑线性控制施工方法，对采用挂篮悬臂浇筑施工方法的变截面桥梁进行轴线、标高、结构应力的线形控制，确保施工过程中结构的可靠度和安全，确保合龙精度以及成桥后的桥面线形、内力符合设计要求。本发明具有以下几个优点：1、结合桥梁的结构和施工特点，在严格控制各控制截面的挠度和轴线横向偏移的同时，兼顾应力发展情况，保证实测应力值在设计允许范围内；2、为施工提供数据支撑，有利于挂篮底模标高调整，保障变截面桥梁整体线形，确保合龙精度；3、提高施工质量，保障施工安全，加快挂篮施工进度，节省工期。
