摘要
工程中遇到的复杂临时边坡,普遍具有安全储备要求较低且使用时长较短的特点,这类边坡在不具备放坡条件时,如果采用抗滑桩、预应力锚索框格梁等传统支护措施进行防护,则容易造成较大的工程浪费。采用微型钢骨桩+预应力锚索组成的“双柔性”支护结构,在满足工程安全需求的前提下,具有施工简便,造价合理,占地面积小,地质、地形适应能力强等优点,可在类似工程中进一步推广应用。
The complex temporary slopes encountered in engineering generally have the characteristics of low safety reserve requirements and short service life.When these slopes do not have slope conditions,traditional support measures such as anti-skid piles and prestressed anchor cable frame beams are used for protection,which can easily cause significant engineering waste.The“double flexible”support structure composed of micro steel frame piles and prestressed anchor cables has the advantages of simple construction,reasonable cost,small footprint,and strong adaptability to geology and terrain,while meeting the safety requirements of the project.It can be further promoted and applied in similar projects.
