With the rapid development of industry in China, the number of gas pipelines that are proposed or under construction is increasing year by year. Accidents such as fire, explosion, and toxic diffusion inevitably happen, which often cause a large number of casualties and property losses. It is increasingly important to analyze the risk along the gas pipelines realistically and to suitably plan, and utilize the surrounding land based on the risk analysis results, thereby reducing the hazards. A theoretical system for risk assessment along the gas pipelines is proposed in this paper. Risks of various major accidents are considered together, superposition effect is analyzed. After the individual risk distribution is obtained, risk zones are divided according to corresponding individual risk value of HSE, and land-use planning suggestions are proposed. Finally, a natural gas pipeline in China is used as an example to illustrate the risk assessment process and its application in urban land-use planning. The proposed method has a certain theoretical and practical significance in establishing and improving risk analysis along the gas pipeline and urban land-use planning. (C) 2013 Elsevier Ltd.
