大型铁路客站基坑围护技术研究
|
摘要
党的十六大以来,我国高速铁路建设如火如荼,与此相适应,现代化铁路客站建设也正在全国范围全面展开,对该类工程围护设计和施工组织的研究将给其他类似工程带来一定的借鉴和参考。
杭州东站枢纽工程在大型铁路枢纽工程建设中有很强的代表性,如工程建设工期紧张；站房作为交通枢纽,处于中心位置,一般下部有地铁穿越,周边有广场配套、铁路站场、市政道路需平行施工,接口多,结合部多,边界条件多；很多铁路站房还涉及既有铁路线的保护和转线。基坑围护也需结合其特点进行设计和施工组织,有别于以往单体工程。
本论文探讨了杭州东站枢纽工程多种基坑围护设计形式如站房总体围护、既有线防护、地铁基坑围护的选型原则,总结了本工程在施工和设计配合过程中积累的经验,详述了本工程在基坑围护设计选型、施工、试验、监测成果等关键技术。
Since the 16th CPC national congress opened, the construction of China's high-speed railway has been in full swing, mutually adapt to with this, the modernization construction of railway station is launched nationwide. The research on the design of maintaining and arrangement of construction provides references to the similar projects.
The construction of large railway station has its own distinct characteristics, such as the construction, companied with exploration and design, has to be finished in urgent time. As the hub of communications, station equiped with square, railway stands and municipal services way constructed simultaneously, lies in the center of city, under which the subway goes through.
The construction of railway station refers to interface and overlapping, which could not be finished without many conditions. Many railway stations involve the protection and the change of lines. Pits maintaining, distinguished from the monomer project, needs to design and constuct combining with its characteristics.
This thesis discusses the priciples of design on maintaining foundationpit of the Hub Project of Hangzhou East Railway Station, summarizes experience accumulated in the process of design and construction, and expounds the core techniques of the selection of pits maintaining design, construction, test and assessment.
