锚-桩结构治理软基高路堤的研究与应用

Study of anchor pile to support road embankment built on soft-earth foundation

针对在傍山路段侧面软土地基上填筑高路堤的工程问题,设计了锚索-抗滑桩结构支挡堤坡,采用极限平衡法分析了路堤的稳定性,并用有限元法研究了路堤和支挡结构的内力与变形,提出了软基上高路堤填筑的控制标准,证明了提出的控制标准是合理的。

For construction of tall embankment of aside-mountain road on soft earth foundation, anti-slide anchor pile is designed to support embankment. Limit Equilibrium Method is used to analyze stability of road embankment ; and Finite Element Method is used to study inner force ; deformation of embankment and support pile structure. On this basis,the reasonable control standard for filling construction of tall embankment is established.
