摘要： 为解决掘进支护一体机在开挖过程中持续产生大量粉尘，造成洞内粉尘质量浓度长期处于较高水平，影响机械设备运行稳定性和施工人员呼吸系统健康等问题，依托成渝中线伍家湾隧道，采用多台粉尘质量浓度仪同步监测的方法，对掘进支护一体机开挖隧道各工序内粉尘质量浓度开展现场监测，并采用除尘车开展隧道内除尘试验，得出的主要结论为： 1）在隧道掌子面开挖和喷射混凝土阶段，掌子面后方100 m范围内粉尘质量浓度峰值可分别达18 mg/m3和13 mg/m3，隧道内的粉尘质量浓度最高达到了规范允许值的9倍。2）在隧道施工过程中，PM10质量浓度占全尘质量浓度比例的最大值分别为72.4%和62.4%，PM10质量浓度与全尘质量浓度分布规律基本一致。3）当除尘车停放于上台阶进行除尘作业时，除尘效果不佳； 当停放于下台阶进行除尘作业时，除尘车后方50 m范围内的全尘质量浓度及PM10质量浓度显著降低，平均除尘效率可达44%。4）仅采用隧道内机械除尘的方法不足以使空气质量满足规范要求，增加辅助抑尘措施是必要的。

Abstract: Tunnel excavation using an integrated tunneling and support machine generates continuous dust emission at the tunnel face. This emission adversely impacts the respiratory health of in-tunnel workers and the spatial visibility inside the tunnel. Existing research on tunnel dust primarily focuses on tunnels constructed using the drill-and-blast method. However, the dust generation mechanism of mechanically excavated tunnels notably differs from that of drill-and-blast tunnels, making it necessary to conduct targeted research on dust generation. Therefore, a case study is conducted on the Wujiawan Tunnel of the Chengdu-Chongqing Central Line Project. The dust concentration in each construction procedure of the tunnel excavated by an integrated machine is synchronously monitored using multiple dust concentration meters, and dust removal tests inside the tunnel are performed with dust suppression vehicles. The main conclusions are as follows: (1) During tunnel mechanical excavation and shotcreting, the peak dust concentration within 100 m behind the tunnel face reaches 18 mg/m3 and 13 mg/m3, respectively, and the maximum dust concentration in the tunnel reaches 9 times the allowance in the specification. (2) During tunnel construction, the maximum proportions of PM10 concentration in total dust reach 72.4% and 62.4%, respectively. The distribution patterns of PM10 concentration are consistent with the total dust concentration. (3) When the dust collector is set on the upper bench, the dust reduction effect is not good; however, when it is set on the lower bench, the total dust and PM10 concentration within 50 m behind the dust removal vehicle are considerably reduced, and the average dust removal efficiency reaches 44%. (4) Mechanical dust suppression in the tunnel cannot fulfill purified air quality requirements, necessitating auxiliary dust suppression measures.
