Typical engineering application models based on conceptual design of long-short-pile composite foundation

The working mechanisms of long-pile,short-pile and cushion in long-short-pile composite foundation are fully discussed from the point of view of each function. The conceptual design principles of long-short-pile composite foundation are proposed. In the light of conceptual design thought,five typical engineering application models of long-short-pile composite foundation are established,and in the description of each typical model,some suggestions on choosing proper design-construction parameters...
