| Abstract: | The conversion from horizontal adit driving to main tunnel driving of Metro works has great construction difficulties and complex construction procedures.It is proposed,on basis of construction scheme comparison,that full-envelope construction method should be adopted for the conversion from horizontal adit driving to main tunnel driving.The works has already been successfully completed.The works practice demonstrates that full-envelope construction method can provide safe and reliable construction and sign... |
