Experiment Study on Bolts Foundation of Large-Jointed Rock Mass in Transmission Lines

Article Preview

Abstract:

Large-jointed rock mass is the main geological condition of transmission lines of Qingyuan Regions in Guangdong Province. The bolt foundations haven’t be studied and applied in this geological condition. Static load tests of 15 single-bolt foundations and 8 group-bolt foundations were carried out. Experiment study shows that the mechanical characteristics of bolt foundation are suitable for transmission lines in large-jointed rock mass. The design parameters of anchor bar in large-jointed rock mass are derived from the measured data:τa>2359kPa, τb>618kPa, τc>42kPa.
