Design and Application of Long-Short-Pile Composite Foundation

Based on the theory and practice of existing composite foundation, this paper discussed the design idea and introduced the bearing capacity and deformation calculation method of the long-short-pile composite foundation. And it verified the feasibility of this method by engineering example. The results show that: the CM long-short-pile composite foundation which can effectively improve the bearing capacity, reduce the building settlement and differential settlement, and fully exert the potential of soil between piles, has theoretical research and engineering application value.
