海底隧道盾构方案可行性研究

盾构法已经在国内外的地下工程中广泛运用,特别是国外著名的海底盾构隧道,如英吉利海峡隧道、日本东京湾海底公路隧道、荷兰W estersche lde隧道;国内先后用盾构技术建成大连路、复兴东路盾构过江隧道,还有在建的上海翔殷路越江公路隧道、上中路隧道和已经开工建设的上海长江桥隧工程。文中首先论述了国内外大直径、高水压、长距离推进等盾构施工关键技术,并结合珠江口海底隧道的建设条件与国内外的成功实例,对海底隧道盾构方案的可行性进行了初步研究。

Feasibility Research on Shield Scheme of Sumerged Tunnel

Shield method has been used in underground engineering all over the world,especially in oversea submerged tunnel,such as English Channel Tunnel,Tokyo Bay Submerged Highway Tunnel,Holand Westerschelde Tunnel.Using the shield technic,Dalian Road and Fuxing East Road Shield Tunnel traversing the Changjiang River are completed,Shanghai Xiangyin Road Highway Tunnel and Shangzhong Road Tunnel are under construction.and Shanghai Yangtze Bridge-Tunnel Project is also constructing just now.First,the constructing technics of large dimeter,high hydraulic pressure and long distance construction shield tunnel at home and abroad are discussed.Then according to the construction condition of Zhujiang River mouth and successful examples,the primary feasibility research on shield scheme of submerged tunnel is carried out.
