浅谈地下水对公路边坡的影响与防治对策

地下水是导致土质公路边坡失稳滑动破坏的主要原因之一。从孔隙水压力、渗透潜蚀、潜水位升降三方面分析地下水对公路边坡土体造成的危害,针对这些危害,提出了解决的措施,一是阻排地表水,防止水流对公路边坡的冲刷及下渗;二是排除地下水,降低地下水位,减轻或者消除地下水对公路边坡的危害作用。

PRELIMINARY RESEARCH OF IMPACT OF GROUNDWATER ON HIGHWAY SLOPE AND THE COUNTERMEASURES

Groundwater is one of the main factors resulting in instability and sliding failure of the soil slope.The authors analyse the damages of groundwater on the highway slope in three aspects i.e.pore water pressure,permeable suffusion and rising and falling of groundwater level.As to these damages,some countermeasures are put forward that are hindering the surface water to prevent the flow from eroding the highway slope firstly and removing groundwater to lower the groundwater level and to lighten or ameliorate the damages of groundwater on highway slope.
