Abstract
If the ground where a telephone pole is embedded is susceptible to liquefaction during an earthquake, the telephone pole may sink, lean, or even fall down. A series of model shaking tests were conducted to investigate the failure phenomena due to soil liquefaction, and to examine the effectiveness of four types of telephone pole stabilization techniques against liquefaction. Two types of test patterns were conducted to determine the effects of suspended cables on telephone poles during ground shaking.
After showing measured accelerations and excessive pore pressures, and observed horizontal movements and settlements, this paper describes the effectiveness of stablizing techniques. A foundation of crushed grain with net was found to be the most effective against pole damage due to soil liquefaction resistance.
