Application of composite foundation in reinforcement treatment for a highway existing culvert

摘要

The foundation reinforcement method was discussed based on an actual engineering example. The paper analyzes the cause of the fissures happened on a highway existing culvert. The combined reinforcement method with root piles composite foundation and static pressure grouting was adopted for the area that settles obviously. The method of design and construction about the composite foundation was introduced .The practice has proved that good reinforcement effect can be obtained when applying appropriate composite foundation for foundation treatment.
