摘　　要：工程施工地区位于我国高寒地带,具有冬期温度低、持续时间长的特点。结合泥水平衡盾构施工工艺要求,通过大量调研和现场实践,对泥水循环系统采用了合理有效的保温措施,并以现场试验为保障,保证了冬期施工的顺利进行。以长长吉松花江盾构工程为例,详细阐述了在东北低温气候条件下泥水平衡盾构泥水循环及设备保温处理技术。In Northeast China, winter lasts long and the temperature stays very low. Slurry shield construction in this region requires special treatment of the slurry circulation system. Based on extensive investigation and practice, proper insulation measures were tested and adopted for the slurry circulation system. Taking the Changling-Changehun-Jihua shield construction as an example, this paper introduced in detail the slurry circulation system and its insulation technologies in extremely cold areas.
