| Abstract:Back-reaming is a very important step in pipe paving construction with method of trenchless technology. The quality of back-reaming will determine the result of the hole construction. Based on equal-torque principle, the thesis established a mathematical model, and deduced the formula to calculate the diameter of back-reaming. The author also programmed software that can carry out the optimum design, and gave out some rational suggestion. |
