Quality Supervising Station for Building Engineering, Tongan District, Xiamen 361100, China; 2. Department of Environment and Equipment, Fujian University of Technology, Fuzhou 350007, China) Abstract: The overall development of compound foundations techniques is surveyed, some relevant con- cepts of which such as compound foundations, foundation treatment, compound pile foundation, spaced- pile foundation designed in accordance with subsidence control are described. An analysis of subject- to - force mechanism reveals that setting up a matting layer or not or joining the piles to the foundation or not are not the essential conditions for compound foundation. The research orientation of the compound foundations in future is pointed out.
