摘要
通过对兰州南绕城某高速公路隧道进行现场监控量测,分析了现场围岩变形、接触压力和一次模筑混凝土应力的变化规律,对现场围岩的变形状态及支护条件的可靠程度有了更科学的了解。研究成果为隧道的现场施工提供了必要的依据,同时也可为以后类似地质条件下隧道的设计和施工提供借鉴。
Through the lanzhou city south tunnel of an expressway on - site monitoring measurement, the deformation and contact pressure of surrounding rock is analyzed and a model of concrete stress, the strain state of surrounding rock on the spot and the reliability of the supporting conditions have a more scientific understanding. Research results for the site construction of the tunnel provides necessary basis, at the same time can also be used for future similar geological conditions in tunnel design and construction for reference.
