Quantitative Estimation of Pipeline Slope Disaster Risk in China

Abstract China’s economic development is closely related to oil and gas resources, the country investing heavily in pipeline construction. Slope geological hazards seriously affect long-term safe operation of buried pipelines, usually causing leakage, property environmental losses, adverse social impacts. To ensure safety pipelines reduce probability disasters, it necessary predict quantitatively evaluate slope hazards. While there has been much research focus recent years on evaluation disasters stress calculation under hazards, existing methods only provide information occurrence events, not whether a disaster will lead damage. Taking 2015 Xinzhan landslide Guizhou Province, China, as an example, this study used discrete elements simulate events determine risk level scope for damage, then established pipe-soil coupling model impact medium- high-risk areas. The results reference future prevention control.
