隧道断面施工监控量测实施与数据分析

MONITORING IMPLEMENTATION AND DATA ANALYSIS ABOUT A CROSS-SECTION OF THE TUNNEL CONSTRUCTION

结合科山隧道施工过程中围岩周边位移和拱顶下沉监控量测,包括量测方法、测点布置等,经过对现场监控量测数据的整理分析,采用直接根据量测结果判断围岩稳定性和支护系统工作状态的判别标准,能够较为准确地掌握围岩趋于稳定的时间,为保证施工安全、确定合理的二次衬砌施作时间提供了可靠的依据,同时也为以后其他类似隧道工程监控量测的实施提供参考依据和经验。

The article combined the rock surrounding displacement and vaults sink monitoring and measurement of the KeShan Tunnel construction, including the method of measurement and the arrange of the measuring points and so on, analysis of the collation data of the scene monitoring and measuring. Directly based on the results of the measurement criterion to determine the stability of surrounding rock and support system working state, and more accurately grasp the time of surrounding rock stabilized, we provide a reliable basis for construction safety and determine a reasonable construction for secondary lin- ing, and also provide a reference for the future other similar tunnel project monitoring and measuring the implementation and experience.
