摘要
以广州市220 kV航云输变电电力隧道工程为例,针对穿越岩溶地层盾构施工风险进行了分析,重点研究了盾构井端头加固技术、穿越岩溶地层盾构施工技术以及下穿建(构)筑物保护措施等方面的内容,提出了一系列施工技术措施,为今后类似条件施工提供有益的技术参考。
Taking Guangzhou 220 kV shipping transmission power tunnel project as an example, this paper analyzed the shield construction risk cross karst stratum, emphatically researched the shield well end reinforcement technology, cross karst stratum shield construction technology and under cross building（structure） protection measures and other contents, put forward a series of construction technology measures, provided good technical reference for similar construction.
