摘要
结合蚌埠市南山郦都项目10#楼(25层)、14#楼(26层)工程实例,介绍了水泥粉煤灰碎石桩(CFG桩)复合地基的作用机理及在蚌埠地区的应用效果,对承载力计算采用了不同方法,使其更加精确;沉降计算采用经验公式求得。水泥粉煤灰碎石桩(CFG桩)复合地基不但具有适应性强、承载力提高幅度大、沉降量小的特点,而且具有较好的经济效益和社会效益。
In this paper,a low-strength concrete mechanism of the composite foundation,using different methods of calculating capacity.it is more accurate.Settlement calculated using the experience equation.Low-intensity concrete pile foundation is not only strong adaptability and capacity growth rate,the characteristics of a small amount of the settlement,Moreover,with good economic and social benefits.
