摘要
《建筑桩基技术规范》(JGJ94-2008)中,钢筋混凝土灌注桩后压浆技术侧摩擦阻力、桩端阻力在粘性土、粉土层中提高系数为一范围。通过鞍钢西区3号连铸主厂房灌注桩桩基础后压浆设计与施工,总结出了具体提高系数,为鞍山西北地区的建设场地和类似土层采用该技术提供了可靠数据。
In the Technical Code for Building Pile Foundations （JGJ94-2008）,the increased coefficient of the side frictional resistance and pile end resistance of reinforcement concrete grouting pile in the clay and silty soil layer is a range. Through the post compressing grouting design and construction of the grouting pile foundation in No.3 main building of Anshan Steel Western Zone,the increased coefficient has been summarized in a concrete number, which provides reliable data for adopting this technology in the construction site of Anshan northwest area and other similar soil layers.
