摘　　要：以成都4层地下室抗浮工程为例,通过对精轧螺纹钢作为压力型抗浮锚杆与普通钢筋作为拉力型抗浮锚杆的计算和基本试验数据进行对比分析,两种抗浮锚杆的试验数据均在规范允许范围内,探讨了在较大水压力情况下采用两种钢筋作为抗浮锚杆的优缺点,在砂卵石地层中采用精轧螺纹钢作为压力型抗浮锚杆单孔极限抗拔承载力更大,获得了良好的经济效益和社会效益。Taking the anti-floating project in the 4-story basement in Chengdu as an example, by comparing and analysing the calculation and basic test data of fine-rolled threaded steel as a pressure-type anti-floating bolt and ordinary steel bar as a tensile anti-floating bolt, the test data of the two anti-floating bolt are within the scope permitted by the specification, and the advantages and disadvantages of using two kinds of steel bars as anti-floating bolt under the condition of large water pressure are discussed. In the use of precision-rolled threaded steel as the pressure-type floating-resistant bolt in sand pebble formation, the single-hole ultimate pull-resistant bearing capacity is greater, and good economic and social benefits have been obtained.
