摘　　要：增量法是目前高层建筑深基坑工程中面向过程设计的常用方法 ,但是对此 ,目前尚缺乏比较全面的分析和理论上的严密论证。为此在理论上阐述了它与针对结果的设计方法不同的数学与力学实质 ,并分析了其对工程设计的影响。最后结合具体算例分析 ,进一步论述了增量法的合理性与科学性。The incremental method,at present,is widely used in the process- oriented design of a deep excavation engineering of high- rise building structures.However,there are few studies to discuss the fundamental theoretical basis of this methodology in more general sense.The computational results helpful for design should be dependent on excavation process.The incremental method which can take the excavation process into account is different from that of the conventional design method in which the excavation process is overlooked.Therefore the natures of mathematics and mechanics of the incremental method as well as its effect on engineering design are examined.Meanwhile,the rationality and reasonability of the incremental method are demonstrated through numerical analyses of a specific example.
