摘要:

在无轨运输方式下,随着隧道掘进距离的增长,洞内车辆调度成为制约盾构高效掘进的关键因素。为优化长距离盾构隧道洞内车辆物料运输流程,提高车辆的运输效率,以苏通GIL综合管廊工程为例,对独头掘进5 468 m的长距离泥水盾构隧道进行物料运输优化,并建立长距离隧道车辆无轨运输优化模型。结果表明: 车辆极限运输长度Lmax和车辆投入数目呈正相关关系,投入6辆双头车可以满足本工程独头掘进5 468 m的运输需求; 车辆最长滞留时间相比于原方案减少131 min。该优化模型可为苏通GIL综合管廊工程洞内物料运输方案提供理论指导,并为类似工程提供参考。

Abstract:

The longdistance and largediameter slurry shield tunneling technology has been widely used in underwater tunnel. With the increase of tunneling distance, the vehicle dispatch in the longdistance tunnel is of great importance to enhance the tunneling efficiency under trackless transportation. It is necessary to optimize the processes of material transportation and improve the transportation efficiency of vehicles in longdistance shield tunnel. In this paper, the material transportation of deadend 5 468 m slurry shield tunneling of Sutong GIL Utility Tunnel is optimized; and optimization model of trackless transportation in longdistance tunnel is established. The results show that: (1) The maximum transportation length Lmax of vehicle is positively correlated to the number of vehicles; and 6 dualheaded trucks are needed to meet the requirement of material transportation for 5 468 m. (2) Compared with the original scheme, the maximum retention time of vehicle in the optimization scheme is decreased by 131 minutes. This optimization model can provide theoretical guidance for materials transportation of Sutong GIL Utility Tunnel, and provide valuable reference for similar projects in the future as well.

Key words: longdistance tunnel, largediameter slurry shield, trackless transportation, model of material transportation
