| Abstract:This paper introduces the importance of pipe jacking resistance in pipe jacking construction, especially in long distance pipe jacking construction. The formulas for calculating jacking resistance in Technical Specification for Pipe Jacking in Water Supply and Drainage Engineering（CECS：2008）and Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering（GB 50268—2008）as well as the formula for calculating jacking force of jacking reinforced concrete pipe made by Japan Sewer Association are listed. In a case of earth pressure balancing pipe jacking engineering in Zhengdong new district, the jacking resistance is tested and studied, the difference between theoretical calculation results and actual value is pointed out and new calculating method for the pipe jacking resistance suitable for Zheng Dong new district is put forward. |
