摘　　要：推导了等应变条件下桩阻作用时的碎石桩复合地基固结方程,并与现场沉降观测数据换算出碎石桩复合地基在路堤施工过程中的固结度对比,二者吻合较好,证明了公式的正确性。沉降观测数据还表明:使用碎石桩处理软土地基能加快地基的固结速率。With the assumption that equal strain and column resistance, the consolidation governing equation for soft ground reinforced by stone column is derived and its solution is obtained. The validity of the proposed equation is conformed through being comparing with the field test subsidence data. The field test subsidence data also show that., stone column is able to accelerate the consolidation rate of soft ground.
