摘　　要：通过收集统计华南地区不同土层下抗浮锚杆的施工数据,主要根据地质勘察报告及MDL-C150D型号锚杆钻机在不同土层中的钻进速度,准确判断土层类别,准确控制锚杆入岩深度,进而较好地达到设计要求,同时为华南地区冲(洪)积岩、粘土、砂土、风化(泥)岩等典型地质条件下的地下工程施工提供一定参考依据。Through collecting statistics the fe asibility of construction data under different soil in South China,mainly according to the geological investigation report and jumbolter to MDL-C150D model in different soil layer in drilling speed,accurate judgment the soil category,accurate control of anchor rod into the depth of the rock,and better meet the design requirements,at the same time for South China Alluvial(Diluvial)rock,clay,sand,weathering(mud),etc.,the geological conditions of typical underground engineering construction to provide certain reference basis.
