Description
技术领域technical field
本实用新型涉及轨道交通技术,特别涉及一种轨道交通高架车站。The utility model relates to rail transit technology, in particular to an elevated rail transit station.
背景技术Background technique
目前,国内轨道交通项目路中高架车站(侧式站台及岛式站台车站)采用独柱结构的比例较高,且均采用现浇钢筋混凝土结构。该结构的优点在于:运营过程中维护工作量较小,工程造价相对较低。At present, the elevated stations (side platforms and island platform stations) of domestic rail transit projects adopt a relatively high proportion of single-column structures, and all of them adopt cast-in-place reinforced concrete structures. The advantage of this structure is that the maintenance workload during operation is relatively small, and the engineering cost is relatively low.
然而,现有技术中的上述使用传统混凝土独柱结构的轨道交通高架车站也存在如下所述的缺点:However, the above-mentioned rail transit elevated station using traditional concrete single column structure in the prior art also has the following disadvantages:
1、传统混凝土独柱结构自重大、构件尺寸大、结构体量大,且结构整体抗侧力体系只有一根独柱,在地震作用下会承受很大的轴力和弯矩。在大震时钢筋混凝土独柱形成的塑性铰延性差,无法很好的消耗结构在震动时的能量,极易发生不可修复的破坏,因此地震作用下结构抗震性能差。1. The traditional concrete single-column structure is self-heavy, the component size is large, the structural volume is large, and the overall lateral force resistance system of the structure has only one single column, which will bear a large axial force and bending moment under the earthquake. During a large earthquake, the plastic hinge formed by a single reinforced concrete column has poor ductility, which cannot consume the energy of the structure during vibration, and is prone to irreparable damage. Therefore, the seismic performance of the structure under earthquake action is poor.
2、传统混凝土独柱结构均采用现场浇筑的方式,施工复杂,一般都需要使用如下的工序:搭设满堂脚手架以浇筑梁板构件;支模板以浇筑梁柱构件;绑扎钢筋等。以上工序均需在现场完成,造成工期长、占用道路周期长、混凝土浇筑困难等缺点。2. The traditional concrete single-column structure adopts the method of on-site pouring, and the construction is complicated. Generally, the following procedures are required: erecting a full hall of scaffolding to pour beam-slab components; supporting formwork to pour beam-column components; binding steel bars, etc. All the above processes need to be completed on site, resulting in disadvantages such as long construction period, long road occupation period, and difficulty in concrete pouring.
3、由于传统混凝土独柱结构的构件尺度大,对城市景观产生不良影响。同时,混凝土结构在施工过程中对周边环境会造成很大的影响和污染。。3. Due to the large size of the components of the traditional concrete single-column structure, it has a negative impact on the urban landscape. At the same time, the concrete structure will have a great impact and pollution on the surrounding environment during the construction process. .
4、传统混凝土独柱结构因自重荷载大,梁柱构件配筋量大,钢筋净距小,绑扎钢筋工程量大,且造成混凝土浇筑困难,难以控制施工质量。4. The traditional concrete single-column structure has a large self-weight load, a large amount of reinforcement for beam-column components, a small clear distance between steel bars, and a large amount of engineering work for binding steel bars, which makes concrete pouring difficult and difficult to control the construction quality.
因此,有必要对现有技术中的轨道交通高架车站结构体系进行改进。Therefore, it is necessary to improve the rail transit elevated station structure system in the prior art.
