| Abstract: | The construction technology for level parallel long-distance large-diameter pipe jacking under complex geotechnical conditions are descried in detail after optimization analysis of the construction scheme,with a level parallel pipe jacking project as an example.The monitoring results of the deformation of the stratum caused by the pipe jacking construction are analyzed.The characteristics of the stratum disturbance during the crossing process is provided.Some countermeasures to control the deformation are recommended and the construction safety is quaranteed. |
