摘要
以某隧道工程为实例,根据围岩的地质条件、现场监控测量数据、超前地质预报等数据来进行控制,通过对台阶上的作业方式进行调整,提高预留沉降量、增加辅助措施,确定施工管理标准,对沉降点位在各个施工段的累计沉降限值进行细分和明确,并针对性地提出了各项限值的加固措施,实现了隧道大变形的胴体管理,保证了隧道工程的施工质量。
Taking a project of tunnel as an example, according to the geological condition of surrounding rock, field monitoring measurement data, advance geological forecast data to control, through the operation mode upon the steps to adjustment, improve the reserved settlement and auxiliary measures, determine the construction management standards, subdivides and defines the accumulated settlement limit value of the settlement point in each construction section, and puts forward the corresponding reinforcement measures of each limit value, realizes the large deformation of the tunnel body management, guarantees the construction quality of tunnel engineering.
