Cable-stayed and suspension cable cooperative system bridge closure measurement and construction method
The invention relates to a cable-stayed and suspension cable cooperative system bridge closure measurement and construction method, which comprises the following steps of: establishing a closure measurement coordinate system by utilizing the characteristic that the centers of lower cross beams of two tower columns are kept stable in the construction process, and then measuring the coordinates of a plurality of preset linear measurement points under the closure measurement coordinate system; the measurement of the two closure gaps is carried out in a coordinate system, and the measured data is associated; linear deviation data of actual linear shapes and theoretical linear shapes of the first beam body and the second beam body corresponding to the four sides of the double-closure gap are calculated according to the coordinates of the linear measuring points, so that the linear shapes of the continuous beam bodies on the four sides of the double-closure gap are observed synchronously without being influenced by environment temperature difference, and the measurement precision of closure is improved; besides, in the construction process, according to the matching relation between the side ring openings of the first beam body and the second beam body and the closure section beam body and the length matching relation between the closure opening and the closure section beam body, closure section matching is guided, and the problems of main beam linear control and closure coordination of the cable-stayed and suspended cable part in the construction process are solved.
本申请涉及一种斜拉悬索协作体系桥合龙测量、施工方法，利用两塔柱下横梁中心在施工过程中保持稳定的特点建立合龙测量坐标系，然后在合龙测量坐标系下通过测量预设的多个线形测点的坐标，使两个合龙口的测量在一个坐标系下进行，将测量的数据进行关联；然后根据多个线形测点的坐标进行计算出双合龙口四侧对应的第一梁体和第二梁体的实际线形与理论线形的线形偏差数据，从而同步观测双合龙口四侧连续梁体线形，不受环境温差影响，提高了合龙的测量精度；另外，在施工过程中根据第一梁体和第二梁体的侧环口与合龙段梁体的匹配关系，合龙口与合龙段梁体的长度匹配关系，指导合龙段匹配，解决了施工过程斜拉和悬索部分主梁线形控制和合龙协调难题。
