摘要:
西南山区铁路路基工程由于受高速铁路线性、站场位置等因素控制，不可避免会遇到边坡高度超常规情况。云桂铁路昆明南车站中强膨胀土路堑高边坡近50 m，地质条件较差，岩土力学强度低，又处于高烈度地震区。针对该路堑高边坡，文章研究了桩板墙强支挡结构结合缓边坡、大平台、坡面框架锚杆的综合处理措施确保该高烈度地震区中强膨胀土路堑边坡长期稳定，可为同类工程提供技术参考。
Abstract:
For the railway subgrade engineering in southwestern mountainous area, unconventional slope height cannot be avoided because of the controlling factors such as railwayline, station yard sites, etc. The strong expansive soil cut high slope of Kunming south station on Yun Gui railway is about 50 m,which is in high intensity seismic region with poor geological conditions and low soil mechanics intensity. So the combined treatment measures of strong retaining structure of slab-pile wall are combined with slow slope, large platform and slope frame anchor are studied to ensure long-term stability of strong expansive soil cut high slope in high-intensity earthquake zone has-expansion soil. It can provide technical reference for similar projects.
