摘　　要：以黄榄快速干线(西段)工程为例,介绍了采用预应力管桩处理深厚淤泥和淤泥质粘土的实践。2010年2月工程开始施工,2010年8月预应力管桩全部施工完成,2011年1月路堤填土完成。路基沉降监测表明,路基沉降稳定后工后沉降约220mm,与设计基本吻合,表明采用预应力管桩处理深厚淤泥和淤泥质粘土是一种技术可行的方法,对类似工程有借鉴作用。This paper introduces the application of prestressed concrete pipe pile supported embankment over thick soft muck and mucky soils during the construction of Huanglan （west section） expressway. The pile installation started in February 2010 and completed in August 2010. The embankment construction was completed in January 2011. The settlement monitoring re- sults indicated that the maximum post construction settlement was 220 mm. This settlement value is consistent with tile predic- ted value during the design stage.
