Discussion on Construction Technology of Exposed Shallow Complex Stratum in Shaft and Related Engineering
LIU Ning
Abstract：Combined with the stratigraphic characteristics of comprehensive analysis and formulation of safe and reliable construction scheme are the premise to ensure the smooth implementation of the pro-ject in the process of shaft and related engineering construction of exposed shallow complex strata .By analyzing unit used ground pipe roof grouting ,jet grouting pile reinforcement method ,freezing method process ,Ying panhao shaft used freezing method in construction of the wind tunnel with large cross section and the project successfully passed the thick shallow sand layer with rich water ,having high project quality ,derrick settlement being within the allowable range .
Keywords：Wind tunnelfluidized sand layerfreezing method
