自重湿陷性黄土灌注桩单桩竖向压力设计值的确定

The Ascertainment of Caisson Pile Single Pilevertical Pressure Design Value in The Self Weight Collapsibel Loess Site

以灵宝某工程灌注桩原体试验为背景材料 ,初步探讨自重湿陷性黄土场地灌注桩原体试验未能测得负摩阻力时 ,确定单桩竖向压力设计值的方法 ,以达到既满足工程安全需要 ,又能充分发挥桩基承载能力的目的。

Based on one caisson pile on-the-spot test project in Lingbao,the paper roughly discusses the method to determine the single pile vertical pressure design value in case that caisson pile on-the-project test can’t get negative frictional force.by using this method,me can both meet the need of the safety of the project and make full use of the bearing capacity of the pile.
