| Abstract: | Through the comparative analysis of bbored grouting piles construction method, the optimal pore forming way is chosen. Based on the property of steel casing, the reasonable easing depth and thickness of precession is determined which solves the technical problems of Shanghai-Hangzhou High-speed Railway roodbed overpass rail transit line 9 at close distance. Thus the demand of the piles construction of subgrade section is satisfied, and it can ensure the operation safety of subway tunnel. |
