Description
技术领域technical field
本发明属于地下工程、轨道交通以及隧道施工技术领域，具体涉及一种地铁车站与隧道结合的地下结构及其施工方法。The invention belongs to the technical fields of underground engineering, rail transit and tunnel construction, and particularly relates to an underground structure combining a subway station and a tunnel and a construction method thereof.
背景技术Background technique
近年来，随着城市化建设的不断加快，人口数量的不断增加，人们的交通出行需求量日益增长；交通是城市发展的基础，城市轨道交通作为缓解城市交通拥堵、引导城镇空间布局合理拓展、促进城市人口合理迁移的高速、大运量骨干交通方式。截至2021年，中国内地累计有45个城市建成投运城轨线路7978.2公里，同比增长18.54%，行业增速明显回升。In recent years, with the continuous acceleration of urbanization construction and the continuous increase of the population, people's demand for transportation is increasing day by day; transportation is the basis of urban development, urban rail transit is used to alleviate urban traffic congestion, guide the rational expansion of urban space layout, A high-speed and large-capacity backbone transportation mode that promotes reasonable urban population migration. As of 2021, a total of 7,978.2 kilometers of urban rail lines have been built and put into operation in 45 cities in mainland China, a year-on-year increase of 18.54%, and the industry growth rate has rebounded significantly.
地铁是由线路、列车、车站等组成的交通体系，轨道交通线路隧道施工一般采用盾构施工，车站通常采用明挖、暗挖等方法进行施工；隧道盾构施工前，通常需要在车站位置设置盾构接收井及始发井，先施工车站，盾构井完成后才能进行盾构吊装就位，然后才能进行隧道施工，效率低下，工期较长；常规车站标准段开挖深度在16-18m，盾构井基坑深度较深通常在22-24m左右，施工风险增大，成本增高。The subway is a transportation system composed of lines, trains, stations, etc. The tunnel construction of rail transit lines generally adopts shield construction, and the stations usually adopt open-cut, undercut and other methods for construction; before tunnel shield construction, it is usually necessary to set For the shield receiving well and the starting well, the station is constructed first, and the shield can be hoisted into place after the shield well is completed, and then the tunnel construction can be carried out, which is inefficient and has a long construction period; the excavation depth of the standard section of the conventional station is 16-18m , the depth of the shield well foundation pit is usually about 22-24m, the construction risk increases, and the cost increases.
目前国内外有大盾构暗挖车站施工的一些案例，比如日本地铁的压梁法、北京地铁的大盾构扩挖法，均是采用暗挖施工的车站，施工较为复杂，施工风险较高。At present, there are some cases of the construction of large shield underground excavation stations at home and abroad, such as the compression beam method of the Japanese subway and the large shield expansion method of the Beijing subway. .
以上方案均因为地面场地限制，采用暗挖扩挖法进行施工，工法繁琐，施工难度大，周期长，造价高；另外地铁的设备、通风、通信、管线等需要找场地进行安置或特殊设计，此外出地面的出入口等施工也较为不便；因此对于轨道交通而言，隧道一般采用盾构施工，而地铁车站绝大部分仍然采用明挖施工。Due to the limitation of the ground space, the above schemes are constructed by the method of underground excavation and expansion. The construction method is cumbersome, the construction is difficult, the period is long, and the cost is high; in addition, the subway equipment, ventilation, communication, pipelines, etc. need to find a site for resettlement or special design. In addition, the construction of entrances and exits out of the ground is also relatively inconvenient; therefore, for rail transit, shield construction is generally used for tunnels, while most subway stations still use open-cut construction.
