摘要
在长达 10多年的现场观测基础上 ,分析研究了工后沉降严重的连云港既有铁路软土路基的下沉规律 ,准确地预测了后期工后沉降。通过路基对称破坏形态分析 ,总结了考虑填土张性裂缝的稳定检算方法 ,并对采用该方法计算的安全系数与侧向变形、路基严重下沉、路基沉降计算的关系等进行了分析。
On the basis of decadal measurement this paper analyzes the settlement of railway on soft clay ground in Lianyungang.Besides it accurately predicts residual settlement after construction.According to failure mode of soft clay ground,a new stability calculation method,considering tension crack of fill,is provided.Meanwhile,it analyzes the relationship of safety factor calculated by new method with lateral deformation and settlement.
