6、4）《工程测量规范》（GB50026-xx）；　　（4）《铁路工程设计防火规范》（TB10063-xxJ774-xx）；　　（5）《铁路隧道超前地质预报技术指南》（铁建设[xx]105号）。　　4．青荣城际铁路建设指挥部有关要求。　　二．编制原则1．高效、适用原则监控量测是新奥法施工中不可缺少的一项技术内容，是监视围岩和支护稳定性的重要手段，是判断设计、施工是否正确合理的主要依据，是监视施工是否安全可靠的眼睛。　　为了更精确更迅速的了解围岩的动态变化，判定其稳定性，从而保证施工安全。　　本方案的高效运行

7、，能确保预报质量并有效的指导施工，适合本工程所有隧道。　　2．安全原则隧道施工中开挖形成后，必须立即喷射不小于4cm厚的混凝土及时封闭围岩作为初支初喷层，紧跟监控量测，监控量测应在开挖后2-4小时进行，否则工作人员不得进入掌子面作业。　　本方案的操作实施要安全，并能指导安全施工。　　3．符合本单位技术水平的原则本方案拟投入的设备、实施人员均符合本单位现有水平，能确保方案顺利实施。　　三．适用范围适用于青荣城际铁路Ⅳ标段隧道监控量测。　　四．工程概况1．隧道概况本标段共有隧道10座，总长度11.017Km

8、。　　隧道全部位于山东省烟台市境内，地貌形态为剥蚀丘陵，地形高低起伏，部分地段冲沟发育，基岩大部分裸露。　　隧道穿越的地层岩性多为片岩、花岗岩、变质岩等，岩性变化较大。　　隧道概况表见下页。　　2．施工存在的风险根据设计图纸提供的地质资料，不难发现，本标段隧道施工中存在坍塌、冒顶、突水、突泥等风险。　　3．监控量测目的　　（1）通过监控量测了解各施工阶段地层与支护结构的动态变化，把握施工过程中结构所处的安全状态，判断围岩稳定性，支护、衬砌可
