| 摘 要： | 对溜砂坡中注浆工程固砂和生物工程固砂力学机理进行了阐述。花管注浆本身竖向浆柱和侧向浆脉可起锚固效应,相邻浆柱间可起土拱效应;生物工程的植被深根可起锚固效应,盘结的浅根能起加筋效应。以上2种工程措施的有机结合,将发挥各自的优势,从而达到对溜砂坡标本兼治的效果。最后对川藏公路中坝段溜砂坡的整治措施作了简单的描述。

| Abstract: | This paper describes the mechanism of sand fixations by grouting engineering and biological engineering.The grouting veins formed by pipe-grouting act as anchors,and adjacent grouting columns work like soil arches.The deep roots resulted from biological engineering act as anchors,and voluminous flat roots present a reinforcement effect.The authors consider that the combination of civil engineering measures with biological engineering measures can make the best of respective advantages,and thus achieve the effect of managing both its root cause and symptoms.Finally,countermeasures on No.13 sanding-sliding slope in Zhongba section of the Sichuan-Tibet highway are briefly discussed. |
