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。
Through the wasteland on the pipeline, mostly salinized light embankment or less grass embankment, annual rainy season pipe embankment soil loss. Become a normal operation of the pipeline one of the important issues. Through the indoor and outdoor experimental observations, the formation of saline-dike embankment and the mechanism of soil erosion are analyzed. The method of light-moderate saline-alkali embankment restoration vegetation is proposed, and the feasibility of using soil-cement lining for serious salinization dike is analyzed The project cost less than 1/5 masonry masonry. It provides a new way for the salinization of embankment protection.
