摘　　要：通过对陕京三线输气管道工程在陕北境内的十几处黄土崾岘地貌和地质特征进行分析,结合工程实际,以下部为2∶8灰土,上部为3∶7灰土的崾岘加固为模型,对此种崾岘拓宽技术进行受力计算,并与传统的下部为3∶7灰土,上部为2∶8灰土的崾岘加固技术进行沉降数值比较,得出现行的加固处理技术沉降小且工程经济效益好。此外,提出了黄土崾岘拓宽处理施工措施和施工技术要求。The physiognomy and geological characteristics of ten or more strictured loess sections in the northern of Shaanxi Province are analyzed here,which involves the gas transmission pipeline of Shaanxi-Beijing third pipeline.According to practical projects,the reinforcing treatment model of the strictured loess sections with the upper lime soil being 3∶7 and the under lime soil being 2∶8 is analyzed and calculated.Moreever,the present reinforcing treatment technology is compared with the traditional reinforcing technology of the strictured loess sections with the upper lime soil being 2∶8 and the under lime soil being is 3∶7,and the conclusion is drawn that the present reinforcing treatment technology is more practical and economical than the traditional reinforcing treatment technology of strictured loess sections.Furthermore,some treatment measures and technology of reinforcing for strictured loess sections are presented.
