Analysis and Countermeasures on Seismic Damages of Gas Pipeline Network in Wenchuan Earthquake

Based on seismic damage data of gas pipeline network, obtained through scientific investigation in 18 cities/counties, seismic damage appearances of gas pipeline which are made of different materials are summarized and compared, and their impacts on gas supply function are studied. Then the use status of pipeline of different materials and the reasons of causing damages are analyzed. And some earthquake resistant countermeasures are proposed to reduce the seismic damages.
