摘要
随着社会经济建设的发展,基础建设的投入不断加大,作为交通基建领域的一项重要内容,隧道工程的应用越来越多,大量的铁路隧道、公路隧道不断兴建。而隧道工程和边坡密切相关,特别是连拱隧道,由于其跨度大、施工工艺复杂,洞口段极易受到偏压地形以及潜在的滑坡、剥落、崩塌等边坡变形破坏问题的威胁,因此,对隧道洞口边坡稳定性开展研究显得十分重要。此外,在目前国内进行的监控量测与预测控制中,对隧道边坡监测项目的报警指标并没有一个量化的标准,报警体系尚不成熟,因而隧道洞口边坡的监测控制技术研究就显得十分重要。
     本文依托江西省交通厅景婺黄(常)高速公路建设项目办公室科研项目:“隧道群施工若干关键技术研究”,总结了影响隧道边仰坡稳定性的基本因素,对隧道洞口边仰坡的破坏机理进行了研究,提出了边仰坡的基本破坏模式。
     基于大量的监测数据,本文提出了隧道边仰坡破坏的“五阶段”发展模式,分析讨论了岩质隧道边坡稳定性的判定方法,并对洞口段控制技术进行了一定的研究;建立二维弹塑性模型,计算分析不同的进洞方式对隧道边仰坡的影响,归纳总结了目前隧道边仰坡防护措施。
     本文对隧道洞口边仰坡的监测技术进行了研究,重点结合国内外相关规范、实测数据和三维数值模拟计算结果,提出并论证了新的隧道边仰坡稳定性的监测报警指标;结合白洋冲一号隧道实例,论文还运用二维反分析和三维有限元计算分析方法,对实际工程实现施工动态模拟,总结了隧道边仰坡的位移和围岩受力规律。
With the development of social economic, the investment of infrastructure construction is greatly enlarged. As an important part of infrastructural construction of traffic, the application of tunnel is more and more popular. Also, the tunnel has intense relation with slope, especially the twin tunnel. Landform disaster, such as coast, peeling off and dilapidation, is extremely easy induced at the entrance of twin tunnel, as the result of the wide span and complex techniques. Therefore, it is very important to do some researches on the stability of tunnel slope. At present, there is not a uniform quantization standard for the warning index in the tunnel monitor project. The warning system is still immature in monitoring projects. So, it appears very important to research the monitoring control technique.
    The paper depends on the project of "Some Key Technologies Research during Construction of Tunnels", Construction Project Office of Jiangxi Provincial Communications Department of JingWuHuang(Chang) highway. On the basis of large amount of reality measures data, the basic factor of the slope stability is summarized. Also, the destroying mechanism of the slope is analyzed in the paper. Then the basic destroying patterns of the tunnel slop are presented.
    Owing to a great quantity monitoring data, five destroyed stages of the tunnel slope are suggested, and the methods for determining the slope stability are discussed. And the influence on the tunnel slope in different excavating mode is analysisd by using the 2-D elastic-plastic model in the GEOFBA~(?), a finite element package developed in Tongji University. Also, the protecting measure to the tunnel slope is concluded in the paper.
    Also, some reseaches on monitoring techniques for the tunnel slope is carried out in the paper. And the monitor warning index for the tunnel slope is presented by consulting some monitor criterions, reality data and numerical computation results. Finally, dynamical simulation has carried out by the 2-D back analysis and 3-D FEM analysis, based on the 1# of BaiYangChong tunnel in JiangXi Province.
