摘要:

本文在实地调查的基础上,采用标桩法对2006年西部原油成品油管道工程在古浪段造成的水土流失情况进行监测与分析,结果表明:该地区侵蚀类型以风蚀为主,土壤侵蚀模数在2500-5000t/km2?a之间,侵蚀程度为中度。在治理措施上,建议布设削坡和重力式挡墙中的片石垛,并辅助以明渠式引水、防渗和条状护坡等工程措施;同时选择白榆(Ulmus pumila L.)、柠条(Caragana korshinkii Kom.)、扁穗冰草(Agropyron cristatum L.)和苦豆子(Sophora alopecuroides Linn.)等根系发达适应性强的树种草种稳固边坡,防止由于工程所造成的新的水土流失。

Abstract:

This paper is based on the surveying and testing, and analyzes the Soil Erosion situation which is caused by Western Crude Oil Pipeline Engineering in the section of Gulang from 2005 to 2007 using the standard stake method. The result shows that this region is the typical area of wind, the modulus of soil erosion is between 2500 and 5000 t/km2, and the degree of erosion is moderate. In the managing measures, we suggest using some engineering measures for protection, such as laying out rubble mound which is one type of gravity retaining wall, cutting slope assisting and aided by open type water diversion, Seepage control measures, Strip of slope protection and so on. At the same time, we choose Ulmus pumila L., Caragana korshinkii Kom. , Agropyron cristatum L. and Sophora alopecuroides Linn. or other trees which have the developed root and strong adaptability to steady slope to prevent the new soil erosion fellow with the project.
