东海大桥GPS天线阵列变形监测方案设计

Scheme deformation monitoring using GPS antenna array design of for donghai large bridge

介绍了自主研制的GPS天线阵列变形监测系统。根据东海大桥的具体情况,给出两个东海大桥GPS天线阵列变形监测的设计方案。采用该设计方案,建设东海大桥变形监测系统的成本仅为隔河岩模式的31%。

This paper mainly introduces deformation monitoring the using GPS antenna array system, which is developed independently by our team. Then, according to the specific circumstance, it presents two designs for GPS antenna array deformation monitoring of the using Donghai large bridge. Using our designs, the deforma- tion monitoring system for Donghai large bridge will cost only 31 percent of the money spent on the Geheyan model. That is, comparing with the Geheyan model, the first design can save 69,460,000 yuan of the construction expense, while the second one can save 40,830,000 yuan.
