Research on Subsidence Ageing of Soft Soil Roadbed Based on Original Position Monitor

摘要

The stability of soft soil roadbed is a key factor for the properties and quality in motion of highway or railway. The process of stable soft soil roadbed has protracted nature. The stable of soft soil roadbed depend 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.
