摘要
针对广巴高速公路某隧道洞口施工过程中发生的病害,从地形地质因素、气候因素和施工因素3方面全面分析了产生病害的主要原因,并根据现场实测资料,反演分析了该隧道病害发生的全过程,阐述了监控量测在隧道病害预测预防中的重要作用,总结了特殊地段公路隧道开挖及监控量测需要特别注意的问题,为隧道安全施工及监控量测工作提供可借鉴的科学依据.
Taking the defects produced during the construction of a tunnel portal of Guangyuan-Bazhong highway as the research sample, the main reasons of the defects were analyzed from three aspects： its terrain and geology, climate as well as construction factors. Using the measured data on the spot, inverse analysis on the whole process which the tunnel defects produced was made. The important role that the tunnel monitoring measurement plays in forecast and precaution of tunnel defects was explained. Aspects that should be paid attention to during the tunnel excavation and monitoring measurement of special sections of a highway were summarized which provided useful scientific references for the safe implementation of tunnel construction and monitoring measurement in the future.
