| 摘 要： | 软土路基的稳定性对公路的性状与运营质量具有举足轻重的作用,它与路基的内部结构、成分、体量、外界环境有着密切的关系。通过布设边桩点、埋设沉降板、布设测斜管的方式进行沉降观测。在大量的实测数据基础上,运用回归分析原理,对软土路基的沉降时效问题进行了整体性研究,总结出环太湖流域软土路基沉降时效的经验型数学表达式。从锡澄高速公路软土路基沉降时效的预测效果来看,预测结果和实测数据较为吻合。

| Abstract: | The stability of soft soil roadbed is a key factor on the properties and quality in motion of highway. The process of stability of soft soil roadbed has protracted nature. The stability of soft soil roadbed depends on the internal structure, composition, volume and external environment. Based on a vast amount of original position monitoring data, the problem of subsidence ageing of soft soil roadbed was studied as a whole. It summed up the regularity and features of subsidence ageing of soft soil roadbed. The mathematical model of subsidence ageing of soft soil roadbed has been given. |
