基于宁波北仑电厂二期取水隧道盾构出洞口冻结加固工程的现场监测和数值分析的结果,作者系统地讨论了由于土的冻结效应产生的若干技术问题,如地表隆起,土体分层变形和冻土结构周围的未冻土的变形问题。
Based on the results of on-site monitoring and numerical analysis of the freezing consolidation project at the shield tunnel exit of Ningbo Beilun Power Plant’s water intake tunnel, the author systematically discusses several technical problems caused by the soil freezing effect, such as surface uplift and layered deformation of the soil. The problem of deformation of unfrozen soil around frozen soil structures.
