| 摘 要： | 土压平衡盾构在富水地层掘进中常会发生喷涌问题并产生不良后果,以广州地铁6号线的区间隧道工程为实例进行论证.在盾构机配置双螺旋输送器后,除了具有平衡土压的优良性能外,有效的渣土改良措施是防止喷涌发生的重要因素,加强同步注浆管理、阻断盾尾到达土仓的水力联系通道也至关重要,并提出配置双螺旋输送系统后存在的缺点及需要改进之处.

| Abstract: | Water gushing occurred during the EPB shield driving in water-soaked ground in the running tunnel of Guangzhou metro Line 6. After the installation of double screw conveyor,soil pressure was ballanced effectively and the effective improvement of debris played an important role in preventing water gushing. Strengthening the management of synchronous grouting to block the hydraulic passage between shield tail and soil bunker was of equal importance. Drawbacks after equipping double screw conveyor are to be st... |
