摘要
根据苏丹膨胀土地区变电站桩基的特点,通过工程实例,分别对竖向承载力、抗拔承载力、水平承载力的计算以及最小桩长确定等进行了分析,并对规范公式进行了有针对性的修改。变电站各构筑物结构形式具有多样性,应针对不同类型的结构分别设计桩基础;膨胀土地区灌注桩施工宜采用干法钻孔,避免采用泥浆护壁施工,避免水对膨胀土的影响。
According to characteristics of substation pile foundation in swelling soil area of Sudan, determination of minimum pile length and calcu- lations of uplift capacity, vertical and horizontal bearing capacity were respectively analyzed through an engineering case. It also gave pertinent modification on standard formula. The structural forms of substation are diverse, pile foundation should be designed for different types of structure, pile construction in swelling soil area should be dry drilling, avoid using slurry wall construction and the influence of water on expansive soil.
