我国城市公路隧道的设计和施工越来越多地采用新奥法。为了掌握施工中围岩稳定程度与支护受力、变形的力学动态信息,以判断设计、施工的安全性与经济性,隧道开挖后应按照设计要求和现场实际情况立即布点并进行监测,及时将监测数据和意见建议提交给设计、施工、监理等单位,从而达到反馈设计、指导施工。本文结合具体工程项目实施情况,阐述新奥法实际应用情况,可为同类工程项目提供参考和借鉴。
The design and construction of urban road tunnels in China are increasingly adopting the new Austrian law. In order to grasp the stability of surrounding rock and the mechanics dynamic information of deformation and deformation in construction, in order to judge the safety and economy of design and construction, the tunnel excavation should be immediately deployed and monitored according to the design requirements and the actual situation of the site, Promptly submit the monitoring data and suggestions to the design, construction, supervision and other units so as to achieve the feedback design and guide the construction. Based on the implementation of specific projects, this paper expounds the practical application of the new Austrian law, which can provide reference and reference for similar projects.
