结合芜湖长江公路二桥水上勘探工程实例，对深水湍急河流段的水上勘探施工工艺和施工安全管理进行了总结，同时主要针对施工过程中出现的钻探平台准确抛锚定位、固定，护孔套管的固定，护孔套管弯曲、变形、断裂，水位涨、落，护孔套管的伸缩等4大技术难点问题，利用现场现有条件，在保证工期和充分降低成本的情况下，采取了行之有效的技术处理措施，大大降低了钻探成本，顺利完成了钻探施工任务，获得了良好的经济效益和社会效益。
Combining with the on-water exploration engineering example of Wuhu Yangtze river highway bridge，the paper summarizes the construction technology and construction safety management in deep and rushing river section. With the existing conditions, effective technical measures were adopted mainly according to the accurate anchoring and positioning of drilling platform; protecting casing fixation; bending, deformation and fracture of protecting hole casing; fluctuation of the water level and casing expansion, the drilling cost was greatly reduced and the good economic benefit and social benefit were obtained.
