摘要
基岩标是重要的测量基准设施,在洋山深水港东海大桥的工程建设中发挥了控制测量与高程传递的重要作用。标体的结构设计与优化是确保基岩标质量的关键。标体结构包括保护装置、引测装置、导正装置、标底装置、地面装置5大部分,并设GPS测墩,兼有高程控制与平面位置控制的作用。经多年连测,基岩标质量稳定可靠。
During construction of Donghai Bridge of Yangshan Deep-water Port, bedrock bench mark, which is an important surveying datum mark, played an important part in control survey and elevation transmission The structural design and improvement of bedrock bench marks are key points for quality assurance. The mark structure contains five parts： protective device, measure shaft, putright equipment, mark-bottom device and ground device, and GPS measure pier functioning in elevation control and horizontal layout control is arranged as well. The bedrock marks have been proved stable and reliable by measurements in the past four years.
