摘　　要：在对沉降量进行理论计算、数值模拟和离心模型试验的基础上，对南昆线七甸泥炭土路基采用了碎石桩和粉喷桩加固，观测表明软基沉降得到了有效控制，积累了加固深厚泥炭土路基的首次成功经验。According to the theoretical calculation,numerical simulation and centrifugal model test,the peat soil roadbed was reinforced with crushed stone pile and shotcrete pile.Subsidence of the soft soil roadbed was effectively controlled,and a successful experience on reinforcing thick peat soil roadbed has been accumulated for the first time.
