高速公路工程高液限土填筑路基施工技术

Construction Technology of Subgrade with High Liquid Limit Soil in Expressway Engineering

结合某高速公路工程进行高液限土路基填筑施工掺灰试验,制定掺加水泥拌和的高液限土改良措施,并确定最佳掺量和水泥型号,重点对高液限土填筑路基施工工艺进行研究,并对填筑完毕后的高液限土路基压实度和平整度进行检测。

Combined with a highway project,the ash mixing test in high liquid limit soil subgrade filling construction was carried out,the improvement measures ofhigh liquid limit soil mixing with cement were formulated,and the optimal content and cement type were determined.The construction technology ofhigh liquid limit soil filling subgrade was studied with emphasis,and the compactness and flatness of high liquid limit soil subgrade after flling were tested.
