高速公路软土路基稳定性施工控制参数研究

以珠三角地区某软土地基高速公路试验段为工程背景,基于沉降板及位移边桩实测数据,分析了地表沉降及侧向位移变化规律,对填土极限高度进行了理论计算,获得了针对该地区采用袋装砂井处理软基的路堤填筑控制参数。

Research on the stability construction control parameter of soft foundation of freeway

Setting one soft foundation freeway experimental section of the Pearl river delta area as the project background,and based on the settlement plate and displacement side pile measuring data,it analyses the variation regularity of the surface settlement and side displacement,and makes the theoretical calculation to the limit height of filling,and gets the control parameter of using sacked sand drain managing the soft foundation embankment filling.
