Seismic Damage Phenomena and Characteristics of Hydraulic Engineering in Beijing-Tianjin-Tangshan Region during Tangshan Earthquake
aMs7.8great earthquake occurred in the southeastern part of Tangshan City
China
and it was a great earthquake with far-reaching effect in the 20 th century.The earthquake caused tremendous damages to all kinds of hydraulic enginering in Beijing-TianjinTangshan Region.Taking the region within isoseisms of Intensity VI located at longitude 115.5°-119.9°E and latitude 39.0°-40.9°N as study area
based on the results of a statistical analysis
typical seismic damage characteristics and failure types of the hydraulic engineering were given by illustration and tables with visual form.Some factors influencing the seismic damage of hydraulic engineering were analyzed
including ground motion intensity
local geology and site effect
water depth at reservoir upstream before earthquake
engineering structure design
material choice and so on.Finally
some useful practical measures for protecting hydraulic engineering were discussed
to serve the post-earthquake emergency danger removal and improve the seismic performance design of future hydraulic engineering in Beijing-Tianjin-Tangshan Region.
