摘　　要：根据耒宜高速公路路基的地质特殊性 ,研究了适合路基沉降的监测方法 ,对煤层采空区路基、岩溶路基、软土路基在路堤荷载作用下沉降变形进行了监测 ,分析了这些特殊地基条件路基的变形规律 ,对其他类似山区公路建设具有参考价值。In this paper, methods suitable for monitoring the settlements of road foundation were researched based on the specific engineering geological conditions of the Leiyang-Yizhang express highway. The settlements of road foundations were monitored in the underground mined-out zone, Karst land and soft soil area for the analyzing of settlement process and evaluating of stability of road foundations in these areas and other analogous specific foundation conditions.
