In order to ensure safe operation of overlying high-voltage power transmission tower
it must master ground disturbance conditions and forces of supporting structures caused by construction of underpass tunnel.According to field measurements of Lijiachong tunnel which is located beneath a 500 k V high-voltage power transmission tower
relevant monitoring plan and monitoring results are introduced. Monitoring results show that the deformation of surrounding rock tend to be stable during tunnel construction
and safety factors of steel arch support and concrete secondary lining are satisfied with requirement of standard
which proves that construction scheme of tunnel is reasonable
structure is stable and reliable
and sensors can complete relevant monitoring task effectively.
