Abstract: Two-direction reinforced composite foundation has been increasingly applied to engineering practice, but the theoretical research on bearing capacity is relatively lagging behind. The article has reviewed research findings concerning two types of composite foundation, horizontal reinforcement combined with gravel pile and horizontal reinforcement combined with rigid pile. Additionally, unsolved problems in theoretical research in the field are discussed and some suggestions are put forward to promote both theoretical research and treatment technology of two-direction reinforced composite foundation. This will accelerate the general application of two-direction reinforced composite foundation in engineering practice.
