Abstract:Research purposes:Large section loess tunnels of passenger dedicated lines are generally constructed with using many methods together, such as twin sidewall method, CRD method, CD method and the core bench method. For this kind of construction, the applicable ranges of the conventional construction monitoring method and the current code are limited, so it is necessary to do the study to propose the monitoring items, monitoring way, monitoring method and control reference value for monitoring the large section loess tunnel construction.
Research conclusions:Taking monitoring construction of large section loess tunnels of Zhengzhou - Xi’an Passenger Dedicated Line as the background, through the in - situ test and the statistic analyses of the measured data of the 10 tunnels, the conventional method was compared with the non - contact measuring method. After comparing code limit values with the measured data, the monitoring items, monitoring way, monitoring method methods and the control reference values are offered for monitoring construction of large section loess tunnel of passenger dedicated line with using many construction methods together.
