长距离沉管隧道施工通讯工艺及控制方法

摘要

Long distance immersed tunnel communication in the construction face many influential factors,the extension of the tunnel distance lead to increase in the number of repeater,the block of outfitting of the tunnel on the signal coverage,the complex tunnel environment created by cross operation,and adverse weather conditions and so on all put forward higher requirements for communication technology.Therefore,a relatively stable and reliable communication process is needed to meet the daily communication,emergency communications and continuous communication between the tunnel and installation ship in the tunnel.Taking the Hongkong-Zhuhai-Macao Bridge immersed tunnel as an example,combined with the problems encountered in the construction of constantly sum up experience,we studied and explained the communication process and control methods.%长距离沉管隧道通讯在施工中面临的影响因素较多,隧道距离的延长导致的直放站数量增加、隧道内舾装件对信号覆盖的阻隔、难以避免的交叉作业带来的复杂的隧道内环境以及恶劣天气条件等都对通讯工艺提出了更高的要求,因此需要一套相对稳定可靠的通讯工艺,以满足隧道内日常通讯、应急通讯以及沉管安装期间隧道内与安装船之间的不间断通讯.以港珠澳大桥沉管隧道为例,结合施工遇到的问题不断总结经验,对通讯工艺及控制方法进行研究和说明.
