| Abstract: | Laying the entire long distance transmission pipeline into the ditch is one of the difficult issue of construction. Through the simulation of curves of large deformation deflection beams, a mechanics calculation model is built, to analyze the stress and the deformation at different stages and states in the laying process, to find out the most unfavorable stress state, and to determine the key control parameters such as the distance of the lifting point and the height of the hoisting. The results can be used to guide the construction practice and be applied to the pulp pipe, and oil and gas pipeline projects. |
