Influencing Factors and Calculation Method of HDD Strength-oriented
2009
The strength-oriented is a key parameter that decides the accuracy of Horizontal Directional Drilling track. The dominant impacting factors of the strength-oriented are comprehensively analyzed in this paper for designing oriented drilling tracks. A computing model of strength-oriented is deduced and built based on the deformation analytical method of mechanics of the bar materials, and the model is tested and verified in actual construction. A three-dimensional track design system is developed based on this model.
