摘要
结合铁路隧道工程,全面阐述在林区山谷地带隧道群中,采用GPS平面控制网的布测、观测方案、内业数据处理以及贯通误差估计等关键技术,可以有效地改善铁路隧道工程的质量,为工程测量人员提供技术参考。
Combining with railway tunnel engineering,this paper comprehensively expounds that key technologies such as GPS horizontal control network layout,observation scheme,office data processing,and penetration error estimation can effectively improve the quality of railway tunnel engineering and provide technical reference for engineering survey personnel.
