Abstract: At present, China's railway tunnel construction communication mainly uses analog walkie talkie or partial operator network introduction to provide voice communication and data transmission functions for tunnel construction. There is no systematic, reliable, safe and large bandwidth communication bearing platform to support tunnel construction. In this paper, based on the analysis of the communication requirements of intelligent tunnel construction, combined with the characteristics of railway construction, the main functions of communication bearing platform is put forward, the key technologies and solutions are studied, and the system framework is built. It provides reference and support for intelligent construction of railway tunnel in China.

Key words: railway tunnel construction, intelligent construction, communication, bearing network

摘要： 目前国内铁路隧道施工通信主要采用模拟对讲机或部分公网引入等方式为隧道施工提供语音通话和数据传输功能，没有系统、可靠、安全和大带宽的通信承载平台支撑隧道施工作业。在研究分析隧道智能建造通信需求的基础上，结合铁路建设特征，提出通信承载平台的主要功能，构建系统框架，阐述说明关键技术难题和实施方案。为服务我国铁路隧道智能建造提供支撑和借鉴。
