| description | Jacking force is one of the important safety indicators during pipe jacking construction. Existing models for calculating jacking force are widely used in the calculation of jacking force for pipe with regular cross-sections. In this paper, considering pipe-soil interaction, the cross-sectional characteristics and the distribution characteristics between pipe and soil, the calculation equations for the jacking force of circular steel pipe with flange plate were proposed based on the pressure arch theory. The proposed equations were applied to calculate the jacking force for the Olympic Sports Center Subway Station of Line 9 in Shenyang, China, and the results were compared with the field monitoring data to predict the accurate jacking force. Based on the proposed equations, the influences of the flange plate position and steel pipe diameter on earth pressure around the pipe were analyzed. The functional relationship between the earth pressure and the position of flange plate or the pipe diameter was obtained, which provides design basis and theoretical guidance for engineering practice. |
