原始语种摘要: Generally, the maximum differential settlement appears at the overlapping area of existing and new road pavement after highway widening project. However, lots of longitudinal cracks and other kinds of distresses were found on the existing pavement after the widening project of Guangsan Highway. The field investigation was carried out to find out the reason that the large settlement appeared on existing lanes induced by the weak foundation under the existing lanes, which leaded the cracks observed on the existing pavement. In addition, numerical method was adopted to verify this explanation. The parameter sensitivities were studied to discuss the characteristics of subgrade settlement after the highway widening project. Factors considered include different layouts of cement-fly ash-gravel...
