Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.

Research on a New-style Pipeline Inspection Robot System

IntroductionRecently pipe is used widely on the industry,agriculture and daily life. Natural gas and oil supplybecomes one of the fundamental public services and itsimpact on the urban infrastructure is getting larger. Theurban oil/gas pipelines, as they are buried under theground, are prone to external corrosion usually derived bymoisture and chemical agent in soil, which causes materiallosses of the pipe wall. Also, cracks in the welded regionand the da…
