黄土湿陷区油气化工管道地质灾害预防及环境保护研究

Study on the Geological Disaster Prevention and Environmental Control Measures of Oil and Gas Pipelines in Loess Area

黄土地区地质结构具有湿陷性、黄土潜蚀和陷穴及低承载能力的特点,在该地区进行建设的石油化工原料输送管道具有极大的安全风险。针对黄土地区滑坡、高陡边坡、黄土冲沟、崾岘等特殊危险地质条件,提出了油气管道地质灾害预防治理措施;鉴于黄土地区脆弱的生态环境,在石油化工管道施工完毕后必须采取有效的植被恢复策略,针对黄土盖沙区、黄土丘陵沟壑区、土石山区等地形条件提出了植被恢复的措施。

Geological structure in loess area was featured with the collapsibility , latent corrosion , subsidence and low bearing capacity , oil and gas pipelines through the region faced up with great security risk.Based on the special and dangerous geological conditions of the landslide , high and steep slope and loess gully , the geological disaster prevention and environmental control measures of oil and gas pipeline in loess area were put forward.In view of the fragile ecological environment in loess region and according to terrain conditions of the desert cover , loess hilly , gully and mountainous region, vegetation restoration measures were proposed .
