摘要: 本文从长短桩复合地基各组成部分的功能角度,阐述了长桩、短桩、褥垫层的作用机理,提出长短桩复合地基概念设计应遵循的设计原则。应用概念设计思想,建立了长短桩复合地基的五种典型工程应用模式,并在各典型模式的分析说明中,提出设计与施工参数的选用建议。通过在北京某工程的实际应用,显示长短桩复合地基的典型工程应用模式具有较好的实用性。Abstract: 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...
