Abstract:It is necessary to study the characteristics of karst development,distribution of fissures and chemical components as well as moving situation of underground water in limestone before project construction performed on karst foundation. Effective measures should be adopted according to the karst development and engineering conditions. Based on the analysis of karst development and formations in Shaoguan City,the types,mechanisms and characteristics of karst development are presented,and several treatment methods of different karst types such as blasting,leaping over the cover,filling,grouting,drillhole backfill,high pressure jet-grouting,micro-steel pipe pile,dredging or block as well as adapting distance between piles are also proposed. The achieved results show that it will be effective to apply different treatment methods to corresponding karst conditions.
