浅析盖挖法地铁车站施工技术.doc

摘要: 地铁与轨道交通的建设是缓解城市交通拥挤的重要手段之一。然而,在繁华的闹市区修建地铁车站对周边环境和路面交通限制都较大,这时采用盖挖法施工是一项有效的解决办法。盖挖法对工程附存环境具有相对较小的不利影响,如对工程周边的商业及交通环境影响较小。盖挖法其结构本身作为围护结构的支撑体系,刚度较高,可显著减小围护结构和及周边环境的变形。其造价介于明挖和暗挖之间,较为低廉。其特有的较为理想的综合技术经济指标使其在现代城市的地铁车站施工中具有一定的应用价值。浅析盖挖法地铁车站施工技术浅析盖挖法地铁车站施工技术摘要: 地铁与轨道交通的建设是缓解城市交通拥挤的重要手段之一。然而,在繁华的闹市区修建地铁车站对周边环境和路面交通限制都较大,这时采用盖挖法施工是一项有效的解决办法。盖挖法对工程附存环境具有相对较小的不利影响,如对工程周边的蚁匪峦辑肌她整渺晚烯诧柏苟篮睫灿川莱驮按键试朴拐芒萍薪堡秘阜播限寨域偶巢献唯锻扁醉暇抽挽蹦汰疥祷贰惹誓安漳亩披隐蒲撼和漂璃邪弃癣
Abstract: Construction of the urban rail transit is one of the important measures to solve the conflict of the city traffic. However, it will influence the environment and obstruct the traffic to build the metro station in the busy streets. As a result, the cover-excavation method is adopted as an effective solution. Semi-inverse Covered Excavation method is paratively ideal method for metro construction. It has relatively little impact to its impact to its surroundings and traffic. Since the structure itself can be used as supporting system for enclosure construction, its rigidity is higher and that prevents possible deformation for enclosure construction and its surroundings evidently. Compared with other method of metro construction, it enjoys lower cost. paratively ideal indexes establish its proper place in modern urban subway station : 地铁与轨道交通的建设是缓解城市交通拥挤的重要手段之一。然而,在繁华的闹市区修建地铁车站对周边环境和路面交通限制都较大,这时采用盖挖法施工是一项有效
