地震の強さと歩行速度の関係を起震機の振動台上での歩行実験により調べた。実験では,振動は水平単振動とし,進行速度は振動方向に対し45°の方向に,また移動距離は室内を想定し2mとした。歩行速度は約震度4からゆるやかに低下し始め,強くなるにしたがい低下の割合は増加した。床面の振動因子の中で,歩行速度との関係を1因子で表すことができたのは最大速度であり,歩行速度は床面の最大速度が大きくなるにしたがいほぼ直線的に低下した。歩行速度に個人差はあるが,男性,女性による平均歩行速度ではほとんど差がなかった。しかし,女性の方が弱い地震動で歩行限界に達した。地震時の心理的不安等による歩行障害については,今後の研究課題である。<br>(オンラインのみ掲載)

It is useful in planning the safety countermeasures of initial behavior at earthquake that the walking ability at the time shaking by earthquake is studied. In order to investigate the relation between intensity scale of earthquake and walking speed, walking experiments were carried out on the table of the shaking machine. JMA seismic intensity scale was 3∼6 ranges. The walking distance of subjects was 2 m on this hypothesis that man was in a house. Though the number of subjects were the few (male 15, female 15), the followings were chiefly found in this experiment. <br>(1) The average walking speed of subjects at earthquake motion did not change at a standstill so far as JMA seismic intensity scale 4. However, the walking speed gradually began to decrease from JMA seismic intensity 4. The decrease ratio of the walking speed has increased as JMA seismic intensity becomes stronger than 4. <br>(2) It was the maximum speed in the vibration factor of the floor that the walking speed at earthquake motion could be showed with one straight line irrespective of the frequency. The walking speed of subjects has decreased in proportion to the maximum speed of the floor. <br>(3) The average walking speed of male and female were nearly the same speed, but female reached to a walking limit with weaker seismic intensity scale than male. There was a individual difference in the walking speed and limit.
