摘　　要：为了提高高速铁路膨胀土路堑边坡防护处理的施工质量,保证边坡坡面平整稳定,提出高速铁路膨胀土路堑边坡的防护处理方法。通过Winkler模型计算框架梁力学特征,实施框架梁防护施工;在框架梁内设计立体植被垫护坡;分6步实施支撑渗沟的施工,实现高速铁路膨胀土路堑边坡的防护处理。测试结果表明,经本文方法处理后,锚杆安装施工质量、框架梁防护施工质量均符合施工标准,边坡坡面保持平整稳定,边坡点位置、边坡及侧沟平台位置、宽度位移均达到施工标准要求,证明该方法提高了边坡防护处理的施工质量,增强了边坡安全性。In order to improve the construction quality of expansive soil cutting slope protection treatment of high-speed railway and ensure the smooth and stable slope surface,the protective treatment method of expansive soil cutting slope of high-speed railway is proposed.Winkler model is used to calculate the mechanical characteristics of frame beams and implement the protective construction of frame beams,and design three-dimensional vegetation pad slope protection in the frame beam,and the construction of supporting seepage ditch is carried out in six steps to realize the protection treatment of expansive soil cutting slope of high-speed railway.Test results show that after treatment with this method,the bolt installation construction quality,frame beam protection construction quality are conform to the construction standard,the side slope surface remains flat and stable,and slope point position,slope and side ditch platform position,width displacement all meets the construction standard requirements,proved that the method improves the construction quality of slope protection treatment,enhancing the slope safety.
