2008 Hans Cloos lecture. Seismic geo-hazard assessment of engineering sites in China

Original Paper


Based on the fault-block concept, the paper proposes a scheme for the seismic geo-hazard assessment of engineering sites. A general geo-hazard intensity is determined by comparing the basic intensity of the block where the engineering structure is to be located and the influencing intensity associated with the potential epicenter of a strong earthquake in the boundary fault zone. The obtained general intensity is then modified to take into account the local ground conditions and pre-existing geo-hazard level (particularly landslides) to obtain the comprehensive intensity, which is the basis for the seismic geo-hazard level assessment and site planning recommendations. Four dam sites associated with major hydropower stations are discussed, as well as the 100 m high Zipingpo dam which is located close to the epicenter of the Wenchuan earthquake. The results show that a dam designed on an intensity close to that proposed in the paper would be able to resist potential destructive earthquakes without significant distress.
