Field Temperature Data Analysis of the Water Resistance Performance of Freeze-Sealing Pipe Roof Used in Tunnel through Water-Rich Strata
نویسندگان
چکیده
A new presupporting technology named freeze-sealing pipe roof (FSPR) method was adopted in the construction of Gongbei tunnel (Zhuhai, P.R. China), which a critical part Hong Kong-Zhuhai-Macau Bridge (HZMB). The combined pipe-roofing with artificial ground freezing (AGF). water resistance performance FSPR surrounded by water-rich soils studied based on field temperature data. time-dependent changes frozen soil between two adjacent pipes were presented, and thicknesses different freeze period calculated. Besides, remote monitoring system used this research presented systematically. thermal effects Hurricane Nicole wall also observed. results showed that closure can be classified into modes. before excavation had met design requirements excavation, maintained satisfied performance.
