小议公路路基病害的分析与防治

Discussion on Highway Foundation Disease and Prevention

路基是道路的基础,更是保证路面质量的关键。然而,在现实中,由于需要反复承受各种荷载和自然因素的作用,会导致路基的形状、边坡坡度发生改变,严重影响了路面的质量和稳定性。由于所处地区的差异,产生的路基病害也是多种多样的,最常见有边坡崩塌、滑塌,路基变形等,产生的原因涉及土质、人为的破坏、养护和管理等因素。彻底的控制路基病害的产生是不现实的,因此,只能找出其产生的原因并做好防范,采取一系列切实可行的措施,将其产生的可能性降到最低程度。本文论述了不同地区公路路基病害的主要类型及其危害,分析了其产生的原因,并提出了一些切实可行的防治措施,切实保障路面质量和稳定性。

Road embankment is the road foundation and the key to ensure pavement quality.However,in reality,since it has to bear the various load and natural factor,the shape of highway foundation tend to be changed,change of slope which will seriously affect the quality and stability of pavement.Because differences in their locations,the resulting disease is also various such as the landslide,slump,subgrade deformation.The causes involves soil quality,human destruction,conservation and management factors.Compelte control of road foundation disease is unrealistic.Therefore,we could only find out the causes and do well in provention and take a series of practical measures to minimize the possibility of happening to the lowest point.The paper discussed the main types and risks of highway foundation disease in different areas and analyzed the causes and proposed some practical proventive measures to ensure pavement quality and stability.
