| Abstract: | A mechanical model of glass fiber reinforced plastics(GFRP) jacking pipe under eccentric load is established according to the engineering practice.Theoretical analysis is developed based on this model and contrasted with that under axial load.The calculation method on the maximum allowable deflection angle and splay length of GFRP jacking pipe joint are obtained.Finally,an example is given to show that the theoretical analysis is right.These results can be use of to instruct the GFRP jacking pipe design and... |
