Prediction Model for Surface Deformation Caused by Horizontal Directional Drilling Power Pipelining
During horizontal directional drilling power pipelining,the near-surface excavation engineering,it is unavoidable to disturb the adjacent strata and cause strata damage,especially the surface deformation,which may cause the collapse or uplift of the formation,consequently the subsidence of ground,road and buildings and oozing slurry,etc.; even seriously the breakage of the underground pipeline,affecting the transmission of electricity,gas,telecommunications,water and oil.Based on the stochastic medium theory,this paper makes an in-depth research on the abovementioned surface deformation problem.From the perspectives of both uniform convergence and non-uniform convergence,the prediction model for surface deformation is set up,and the calculation formula is defined for surface settlement and horizontal deformation,etc.this research can provide reference for the design and construction of the power line.
