摘要
在修筑高等级公路时 ,常需要开挖而形成高陡路堑边坡 ,边坡稳定与否将影响公路施工和运营的安全。对具有潜在滑动面的不稳定岩质边坡 ,通常采用预应力锚索和锚杆加固以节约工程投资与缩短施工时间。结合某高速公路路堑岩质边坡工程 ,在分析边坡工程地质条件的基础上 ,提出了预应力锚索加固边坡的设计方法和步骤 。
High and steep cut slopes due to excavation are a common sight in building high grade throughways, the slopes stability directly affect the safty of construction and operation of the roads in future. In the case of unstable rock slopes with potential sliding surfaces, the prestressed cable or bolt is usually used to reinforce the slopes so as to cut down engineering cost and shorten time limit for the project. In combination of the cut slope engineering works of an express way the present paper puts forward the designing method to reinforce the slope with prestressed cables, which is useful referentially for similar slope engineering works.
