Abstract
Because of the long-term dissolution of water, the formation of karst caves and fissures in rock formations are called karst. In Karst area, deformation and water damage are the main forms of karst damage to subgrade. Uneven settlement of embankment and instability of subgrade are the concrete manifestations of karst roadbed diseases. Therefore, considering the scale effect of karst, the concrete treatment measures of karst roadbed should be put forward and the principle of prevention and treatment of “ dredging, crossing, reinforcing and blocking ” should be followed, based on the characteristics of various karst forms, such as section funnel, depression, karst cave, solution crack and karst spring.
