桩基沉降计算方法的比较

A comparison of calcuration methods of pile settelement

桩基础固结沉降的计算方法主要有实体深基础法和明德林法，前者又分为不计荷载扩散和两种考虑荷载扩散的方法。文中讨论了各种方法的原理、参数取值的影响，对实体深基础法中产生附加应力的自重荷载提出计算方法，并用一个实际算例比较了各种方法的计算结果。

The consolidation settlement of pile foundation was mainly calculated by deep equivalent footings and Mindlin＇s methods, former were divided into both with or without lateral expansion of the equivalent footing. The principles and effects of parameters of different calculation methods were discussed. A method to evaluate self-weight load in the deep equivalent footings method was given. The calculation results of different calculation methods were compared with a same example.
