本文分析了非开挖作业在岩石地层条件下 ,因钻孔的不平顺性和管道的弹性变形所导致的顶进阻力 ,推导了管道摩擦、管道弯曲、顶管切削作用等产生的顶进力计算公式 ,其理论分析结果为管道顶推装备设计和管道连接设计提供了必要的力学计算依据
This paper analyzes the jacking resistance caused by the irregularity of the borehole and the elastic deformation of the pipeline under the condition of rock formation in the non-excavation work and deduces the heading force caused by pipeline friction, pipe bending and cutting of the pipe jacking Calculation formula, the theoretical analysis results provide the necessary mechanical calculation basis for the design of pipe jacking equipment and pipe connection design
