摘　　要：人工挖孔灌注桩广泛应用于基础施工,施工中经常会遇到地下水、流砂、软土地基、超深开挖支护、有毒有害气体等复杂地质条件。结合马来西亚万捞高架桥项目现场工程实践,对人工挖孔灌注桩在复杂地层中应用的难点进行了总结和探讨。Hand-dug filling piles are widely used in foundation construction. During construction,complicated conditions are often encountered,such as groundwater,flow sand,soft soil foundation,extra deep excavation support,poisonous and harmful gas and so on. In this paper,according to present site engineering practice in Rawang viaduct bridge in Malaysia,difficult points of application of hand-dug filling piles in complicated formations are summarized and discussed.
