大直径钢管桩在高速公路路堤抢险工程中的应用研究

大直径钢管桩具有承载力大，能承受较大的水平力，设计灵活，桩长容易调节，易与上部结构结合，施工简便、快速等特点，非常适用于抢险工程。以大直径钢管排桩为主要支挡结构，结合排水、防渗、注浆等措施的综合处治方法在某高速公路路堤抢险工程中成功的应用，为类似的工程提供了一种新的思路。

Analysis on Application of Large-diameter Steel Pipe Pile in Emergency Works for Highway Embankment

Large-diameter steel pipe pile，due to its characteristics of large bearing capacity，large horizontal thrust withstood，flexible design，pile length be easily adjusted and pile body be easily combined with upper structure，as well as simple and fast construction，is applicable to emergency works.The supporting structure taking large-diameter steel pipe pile rows as the primary，combining with water drainage，seepage control，and grouting measures，is a successful application in emergency works for highway embankment，which provides a new way of thinking for similar engineering.
