摘　　要：本文简要介绍了港珠澳大桥主体工程桥梁DB01标段第一合同段的地质勘察工作和成果;通过对不同桩型单桩承载力的估算与分析,提出了桥墩基础采用嵌岩桩(钢管复合桩)的建议;通过单桩承载力理论计算与试桩数据的对比,确认了提供的桩基参数是准确、可靠的。The engineering Geological Investigation and relevant achievements were described briefly for the first contract period of DB01 bid section of Hong Kong-Zhuhai-Macao Bridge Project. It was proposed to apply rock-socketed piles（steel pipe composite piles）to the bridge abutment foundation by estimating and analyzing the bearing capacities of different types of piles. The pile foundation parameters were proved accurate and reliable by comparing the theoretical calculation results with the experimental data of pile bearing capacity.
