| 摘 要： | 针对宛坪高速公路六车道大跨度双连拱隧道具体条件,通过埋设量测元件对隧道结构进行施工全过程的监测,获得了在施工偏压条件下,各施工阶段的围岩应力、变形、中墙内力及其变化情况。在监测基础上,考虑不同施工阶段的相互影响,对中墙内力进行了深入的分析,得出中墙在隧道开挖过程中的力学特征,并对该隧道中墙进行了安全性评价。

| Abstract: | On the special condition of the six lanes large-span multi-arch tunnel in the Wanping Expressway,the whole tunnel construction was monitored through measuring elements embedment.Surrounding rock pressure,deformation,the middle-wall's internal forces were obtained at any particular stage of the construction process under unsymmetrical pressure.Based on the monitoring data,considering the interactive influences of different construction stages,the internal forces of the inner middle-wall were analyzed and its... |
