本文讨论了工业建设场地施工控制网的必要精度。首先,推导控制网误差与建筑限差之间的比例关系。然后,由联系设备的建筑限差推导出厂区控制网的必要精度,并由柱基的建筑限差推导出厂房控制网的测角、量边精度。 This article discusses the necessary accuracy of construction control networks for industrial construction sites. First, the proportional relationship between the control network error and the building tolerance is derived. Then, the necessary accuracy of the plant control network was derived from the building tolerance of the contact equipment, and the measurement angle and accuracy of the plant control network were deduced from the building tolerance of the column foundation.
