摘　　要：桩基工程是工程建设的关键部分,对工程的投资、工期和安全等有重要影响。笔者以萧山国际机场三期新建项目桩基工程为研究对象,根据建筑物特征和工程地质条件,对桩基选型、持力层选择、桩基承载力、成桩可能性和对周边环境影响进行分析研究。建议桩型选择无挤土效应的钻孔灌注桩,以圆砾作为桩基持力层;试算了单桩竖向抗压承载力特征值和单桩竖向抗拔承载力特征值,认为本桩基工程选择泥浆护壁钻孔灌注桩切实可行,且只要施工时对泥浆处理得当,一般不会对周围环境产生不良影响。本研究结果可为类似工程提供借鉴。Pile foundation engineering is the key part of engineering construction, which has an important impact on the engineering investment, construction period and safety. Taking the pile foundation project of Xiaoshan International Airport Phase Ⅲ new construction project as the research object, according to the building characteristics and engineering geological conditions, the pile foundation selection, pile bearing layer selection, pile foundation bearing capacity, pile formation possibility and the surrounding environmental influence are analyzed and studied. It is recommended to select the bored pile without squeezing soil effect, with round gravel as the pile foundation bearing layer;the characteristic value of vertical compressive bearing capacity of single pile and vertical tensile bearing capacity of single pile is calculated. It is feasible to choose mud retaining wall bored pile for this pile foundation project, and as long as the mud is properly treated, it will generally not have an adverse impact on the surrounding environment. The results of this paper can provide a reference for similar projects.
