Application of small-diameter steel tube soldier piles in slope emergency works

More Information
  • 我国是一个多山的国家,地形复杂,地质条件多样,每年汛期地质灾害发生频繁,易诱发滑坡、崩塌、泥石流等灾害,对国民经济建设、人员安全构成了巨大威胁。由于灾害发生正值主汛期,该类边坡的处治均为抢险工程,工期要求紧。小直径钢管灌注排桩具有施工速度快、开挖量小、对边坡扰动小的优点,特别适合对工期要求紧的抢险工程。本文以西南某公路挡墙病害抢险处治工程为例,分析了边坡挡墙变形机制,通过采用小直径钢管灌注排桩的处治方案,提高了挡墙的抗倾覆能力,有效解决了挡墙基础承载力不足及大规模开挖基坑引发边坡二次滑塌等次生灾害问题,可为类似工程提供参考和借鉴。
