【摘要】 穿越荒原上的输油管堤 ,多为盐碱化的光堤或少草堤 ,每年雨季管堤的土壤大量流失。成为管道正常运营的重要问题之一。通过室内外实验观测 ,分析了盐碱化光堤的形成和土壤侵蚀的机理 ,提出了轻中度盐碱化管堤恢复植被的方法 ,分析了严重盐碱化光堤采用水泥土衬砌的可行性 ;其工程造价不到浆砌石护砌的 1/ 5。为盐碱化管堤的防护 ,提供了新的途径。更多还原

【Abstract】 Most of the petroleum delivering pipe line jetties running across wilderness are bare or grassless. In annual rainy season, precipitation washes heavily away pipe line jetties’ soil. It is one of the principle problems of the normal operation. By lots of indoor and outside experiments, the formation of the bare pipe line jetties and the mechanism of soil erosion are analyzed. Then a vegetation regeneration method for the light mediated alkalized pipe line jetties is put forward, and the feasibility of applying cement soil lining to the serious bare alkalized pipe line jetties is analyzed. The cost of construction is less than 1/5 of cement rubble lining, so a new preventive measure is provided for the alkalized pipe line jetties.更多还原
