摘要

广州南沙国际邮轮码头综合体项目位于珠江入海口三角洲前缘滨海地带,地势低平,软土广泛发育,厚度大,且地下基岩埋深起伏大,各岩土层的压缩性差异大,局部区域由软土直接到强度较高的风化岩,施工难度大。因此,针对沿海地区复杂地质条件下的钻孔灌注桩施工进行了分析,并详细阐述了此种地质条件下的施工经验及方法,为类似工程施工提供借鉴。
        Guangzhou Nansha International Cruise Terminal Complex Project is located in the coastal zone of the delta front of the Pearl River estuary. The terrain is low, the soft soil is widely developed,the thickness is large, and the underground bedrock is deeply undulating, and the compressibility of each rock layer is very different. The local area is directly from soft soil to high-strength weathered rock, which is difficult to construct. Therefore, the construction of bored piles under complex geological conditions in coastal areas was analyzed, and the construction experience and methods under such geological conditions were elaborated, which provided reference for similar construction.
