Civil engineering structures were subject to enormous damage,
considered to be worse than that incurred during the Great Kanto Earthquake, and this
collapse of overhead Shinkansen rails, the collapse of overhead rails
to the Hanshin Hankyu Electric Railways, and the collapse and
overturning of the main supports of the expressway.
This exceedingly shocking form of damage occurred to the sc overhead
support--Mos, considered modern when built, between Ashiya Post Office and
Uozaki. Many of
the other overhead supports which received damage were constructed
and 1975, and most of them were designed and installed in accordance
with the design policies of the day. The removal of these damage supports was
carried out at a frantic pace in order to secure emergency transportation routs and
enable recovery work to continue.
Damage also occurred in underground structures made of the same
material in the
metropolis. Underground structures were always considered safe from
of earthquakes until now, but subsidence also occurred to the roads
ect the Kobe Expressway. This subsidence caused the central pillar on
the underground platform and the station ceiling of Daikai Station to
collapse. It is thought that the main reason for the collapse of the underground station's
central pillar was the fact that the epicenter of the quake was nearby and the
the rate of lateral movement was greater than originally provided for
in the design, which indicates that greater care should be taken on cause
surveys in the future.
Reports have been issued regarding the damage to harbor facilities
earthquakes which struck the areas surrounding Hokkaido between 1993
The Hanshin earthquake also inflicted damage on harbour facilities,
but the scale of the damage exceeded anything ever experienced before.
Immense damage was especially inflicted upon the caisson sheet
breakwaters of man-made islands such as Port Island and Rokko Island. The damagereceived by the
harbor facilities on the East Kobe Wharf included heavy subsidence of
(approximately 3 to 4 meters) owing to polder liquification of the
banks. Similar forms of damage appeared all over this area, and it
has been cal
culated that a minimum of three years and a budget of 940 billion
will be required to effect recovery.
The Hanshin earthquake inflicted enormous damage on civil engineering
, and it is thought that the cause of this damage will be solved by
From now on we will clarify the damage that could have been foreseen
with the use of these considerations and establish methods of obtaining damage
in the immediate aftermath of an earthquake.
We are also looking into the possibility of reviewing anti-earthquake
capabilities to ensure hospitals, schools and other places of evacuation can
remain free from disaster by analyzing the flow and process of the damage.
