DAMAGE OF RIGID FRAME VIADUCT ESTIMATED BY MICROTREMOR MEASUREMENT
|
抄録（英）：
The 1993 Hokkaido Nansei-Oki Earthquake gave serious damage to the rigid frame viaducts in Kaikyo-Line. We measured microtremors of the rigid frame viaducts in this line to clarify the cause of the damage. Main results are as follows: (1) The rigidities of the severe damaged rigid frame viaducts are 40-60% of the non-damaged one. (2) The natural frequencies of the electric poles which are the same kind of damaged one are estimated around 1.8-2.0Hz in HT-direction. These values are almost same as the natural frequency of surface ground under the damaged electric poles. The natural frequency of the non-damaged electric pole nearby the damaged one is estimated 3.0Hz in HT-direction.
