摘要
通过对同类工程对比分析的方法,以南京长江隧道和杨子江隧道工程实例为基础,指出在高水压、超浅埋、长距离、高强度的卵石地层修建超大直径盾构隧道应掌握的关键技术。尤其是在恶劣的复合地质条件下,如何考虑设计盾构开挖刀具,延长盾构刀具的使用寿命,以及重视工程水文地质的研究并针对性的部署应对措施是大直径穿江盾构隧道工程成败的关键,寄希望能对国内外同类工程建设发挥一定的建设性作用。
Analysis to the similar both project of Nanjing, on the basis of the Nanjing Changjiang Tunnel project, points out the key technique should be grasped to build super-large diameter shield tunnel in geology of high pressure, super shallow cover,long distance, high strength gravel. Especially, it is the key to the construction of the super-large diameter shield cross-rival tunnel project on how to design of shield cutters, prolong the service life of shield cutters, and emphasize the research of hydrology geology and the counter measures for construction in the condition of bad geology. Hoping to play more effect on similar project at home and abroad.
