摘要
基于国内某大直径水下隧道工程特点,针对大直径泥水盾构在穿越含水砂砾和强风化砾岩等地层过程中出现的地表坍塌、盾构结泥饼、盾构刀盘被困等故障,在分析原因的基础上,提出针对性的处治技术和施工建议。
Based on the characteristics of a large-diameter underwater tunnel project in China, this paper analyzed the reasons of some accidents in large-diameter cement shield project passing through water-rich gravel stratum and severely-weathered conglomerate rock stratum, such as ground surface collapse, incrusted shield and trapped shield head, etc., and proposed proper treatment techniques and construction suggestion.
