地面出入式盾构法隧道施工技术研究综述

地面出入式盾构(GPST)由日本株式会社大林组研发,作为一种新型盾构隧道施工方法,无需传统盾构的端头工作井,明显减小对周围环境的影响,同时缩短工期。该技术目前的实践工程较少,存在多方面工程技术难题。根据已有研究资料,阐述地面出入式盾构的相关技术难题,主要从隧道衬砌、盾构姿态、同步注浆等几个方面进行总结,分析现有研究不足之处,提出需要进一步研究的方向和研究思路。

REVIEW OF GROUND PENETRATING SHIELD TUNNEL'S CONSTRUCTION TECHNICAL

The ground penetrating shield tunnel was invented by Japanese Co.,Ltd.,obayashi Corporation organizations.As a new tunnel's construction method that can works without working shaft and reduce impact on the surrounding environment obviously,while shortening the duration.The current practice of the technology is less,there are many aspects of engineering and technical problems.According to the already existing research data,this paper elaborated technical problems about ground penetrating shield tunnel,and summarized by tunnel lining,shield attitude,simultaneous grouting and so on.Meanwhile this paper propose further subject and further research ideas.
