摘要:
针对预埋滑槽技术在磁浮交通盾构隧道中尚无应用的现状，以长沙磁浮快线东延线下穿机场防吹坪区段盾构管片结构设计方案为依托，研究了预埋滑槽技术在磁浮隧道中的适用性，并论证了该技术在磁浮线隧道中应用的可靠性。研究表明，预埋滑槽技术可提高盾构隧道主体结构的整体安全，且该技术不会对盾构隧道结构造成损伤，能延长磁浮隧道的使用寿命。
Abstracts:
In view of the current situation that the embedded chute technology has not been applied in maglev shield tunnel, the applicability of the embedded chute technology in maglev tunnel is studied based on the shield segment structure design scheme of the east extension of Changsha Maglev Express line that underpasses airport blast pad zone. Reliability of applying the technology in maglev tunnel is discussed. Research shows that the embedded chute technology can improve the overall safety of the main structure of shield tunnel, and will not damage the shield tunnel structure, prolonging the service life of maglev tunnel.
