Engineering Countermeasure and Bias Voltage Characteristics of Qianyang Tunnel for Longpu Highway
Dou He · Soil Engineering and Foundation · 2010
Theoretical analysis of bias voltage characteristics have been carried out for Qianyang left tunnel in Longpu highway.The cause of bias voltage was illustrated form terrain features,geological conditions and so on.Through theory analysis and calculation of engineering monitoring results,the value of bias voltage was defined for this section of tunnel.Furthermore,the construction program was proposed for controlling bias voltage of this tunnel.
