摘要
采用半盖挖法可以有效减小城市交通与车站施工之间的相互干扰。结合天津地铁某车站,在对半盖挖法关键施工技术分析的基础上,对钢管柱施工、盖明挖结合段不均匀沉降控制提出相应的处理措施。监测结果表明,盖挖段和明挖段受力和变形具有不同的变化规律,盖挖段受力较大,变形较小。实践证明,半盖挖法具有较好的技术经济效益,有着广泛的应用前景。
Semi-covered method can effectively reduce mutual interference between urban traffic and subway construction. Combined with a subway station in Tianjin, this paper proposed the way to control the construction of steel tube column and uneven settlement based on the analysis of the key technology of semi-covered method. Monitoring results show that it has different variation the in open cut section and cover excavation section. Practice has proved that this method has good technological and economic benefit.
