Study on Construction Technology of Chengdu Metro Line1 Shield Interval passing through Parking Lot Access Line |
| |
| Abstract: | Because buildings are dense in cities, the development and utilization of urban underground space will inevitably have an impact on the projects already built on the ground, so that the surrounding environment of the already-built projects will be changed and even unpredictable risks may even occur. With the first phase of Phase Ⅲ of Chengdu Metro Line 1 passing through Dongsi parking lot access line as an example, some beneficial attempts were made in this paper from the aspects of reinforcement measures at early stage, construction control measures and construction monitoring measures. Also, a set of construction technology of metro shield interval passing through the parking lot access line was formed and it was verified during the construction that the cumulative settlement displacement is within the safe range of displacement. |
