摘要
红层堆积体强度差,自稳能力低,常给所在区域的公路边坡带来灾害隐患。微型桩桩径小,施工便捷,其组合结构可抵抗较大的滑坡推力。文章以广元至巴中高速公路K51边坡工程应用为例,说明微型桩组合结构在边坡防治中具有较好的效果。
Redbed accumulated mass always brings disaster risks to highway slopes in its location due to its poor strength and low self-stability.Micro pile structure,with small diameter and simple construction,can resist larger landslide thrust.Taking K51 slope engineering of Guangyuan-Bazhong Expressway,this paper describes micro pile composite structure has good effect in slope protection.
