高含水量软土地区路面破损调查与分析

Investigation and Analysis of Pavement Damage in High Water Content Soft Soil Region

该文通过对高含水量软土地区修筑的城市道路进行破损调查,对其主要破损形态进行了分类,对出现的破损原因进行了初步分析,分析发现,由于地基含水量过高,使得路基强度不足,是导致路面出现沉陷、开裂以及其它伴生裂缝的主要原因。建议对于该地区应采用具有良好水稳性材料进行土基加固。

The article classifies the main damage statuses by the damage investigation of the urban roads built in the high water content soft soil regions,and preliminarily analyzes the damage causes. It is found that the subgrade with the high water content to make the roadbed strength insufficient is the main cause to lead the pavement sinking,crazing and the other associated cracks. The article suggests that the good water stabilized material should be used to reinforce the soil foundation in this region.
