Study on Capillarity Water Rise in Subgrade Soil
Many highways in China cross irrigation area of farm land. The water in rivers and ponds by two sides of roads can flush back into subgrade, and results in more water in subgrade soil, subgrade deformation and lowered capacity. With reconstruction and extension of Zhengzhou-Luohe segment in Jing–Zhu Highway as the research target, this study investigated the method for preventing underground water from entering subgrade. Through studying on capillarity water rise in typical soil of Zhengzhou–Luohe segment, we found out water rise pattern, predicted capillarity water rise and obtained the method for preventing capillarity water from rising into subgrade.
