Bridge segment prefabricating construction linear error adjusting method
The invention relates to the technical field of bridge construction control, and particularly relates to a bridge segment prefabricated construction linear error adjusting method. The method comprisesthe following steps: S1, acquiring nominal coordinates of a first segment; S2, based on the nominal coordinates, acquiring theoretical matching coordinates of the segment, and taking the segment as amatching beam of a next segment; S3, pouring concrete of the next section, and before an inner mold is dismantled, collecting and obtaining matching measurement coordinates of a matching beam and reference measurement coordinates of the next segment; S4, establishing a relational expression of theoretical matching coordinates and the matching measurement coordinates with respect to translation, rotation and scaling scale parameters, and solving the relational expression; S5, calculating the nominal coordinates of the next section according to the solved parameters and the reference measurement coordinates; and S6, based on the nominal coordinates of the next segment, repeating the steps S2 to S5 to complete pouring of all the segments. Problems that in the prior art, an influence of scaling scale parameters on control points is ignored so that prefabricated linear error control precision is not enough, and a prefabricated linear smoothness degree is influenced can be solved.
本发明涉及桥梁施工控制技术领域，具体涉及一种桥梁节段预制施工线形误差调整方法，包括以下步骤：S1：获取首个节段的名义坐标；S2：基于该名义坐标，得到该节段的理论匹配坐标，将该节段作为下一节段的匹配梁；S3：浇筑下一节段混凝土，在拆除内模前，采集得到该匹配梁的匹配测量坐标和下一节段的参考测量坐标；S4：建立理论匹配坐标与匹配测量坐标关于平移、旋转和缩放尺度参数的关系式并求解；S5：根据求解的参数和参考测量坐标计算下一节段名义坐标；S6：基于该下一节段的名义坐标，重复步骤S2至S5，以完成所有节段浇筑。能解决现有技术中忽略缩放尺度参数对控制点影响，导致预制线形误差控制精度不够，影响预制线形平顺程度的问题。
