摘　　要：本文根据卵石层、含砾石砂岩、海洋软土层等地质条件下钻孔桩施工经验,结合国内三个典型地区的工程实例,着重分析了泥浆比重确定、清孔工艺改进、终孔岩层的判断、水下混凝土灌注工艺等共同规律,给出了对应不同地质条件的施工技术参数以供实践工作参考。The pile constructional technique was summarized according to the constructional experience that came from several bridge in typical region in this paper. Common law about the proportion of mud, pile construction technology, rock samples judgment, pouring concrete technology was gived to guide the pile construction in the condition of gravel layer, sandstone with gravel, soft soil in deep sea.
