摘要
京沪高速铁路徐州车站站房工程采用钻孔灌注桩基础,针对场地特点并经方案比较,在岩层中采用旋挖取芯钻进,成孔速度快,桩身质量好,入岩深度合格率达100%。
Xuzhou railway station of Beijing-Shanghai high-speed railway adopts bored and grouted pile foundation. After consideration of site conditions and scheme comparison, rotary core drilling technique is used to realize fast hole forming and high-quality pile body. Rock drilling depth qualification rate is as high as 100%.
