一、桥梁工程施工的测量控制进行桥梁施工,先期测量与控制是质量控制环节中的重中之重。特别是在地质环境与施工条件复杂的情况下,测量定位控制工作更要精益求精。施工测量放样贯穿施工的全过程,施工放样所采用的测量点均以首级控制网点为基础。施工测量放样应 First, the bridge construction measurement and control bridge construction, measurement and control is the quality control section of the most important. Especially in the case of complex geological environment and construction conditions, measurement and positioning control work should be more excellence. The whole process of construction survey and setting out through the construction, the measurement points used in construction setting out are based on the primary control network. Construction survey should be lofted
