摘　　要：《土工试验方法标准(2007版)》(GB/T 50123-1999)对直剪试验速率有专门规定。为分析直剪速率对直剪固结快剪指标强度的影响,对上海地区原状土样进行不同剪切速率的对比试验,以验证剪切速率对固结快剪试验指标的影响。结果表明,剪切速率会直接影响直剪固结快剪试验的强度指标。There are the special stipulations for the direct shear test rate in Geotechnical Testing Method Standard(2007 Edition)(GB/T 50123-1999). In order to analyze the influence of direct shear rate on the direct shear consolidation fast shear index strength, the different shear rates of undistributed soil samples in Shanghai are compared and tested to verify the influence of shearing rate on consolidation fast shear index.The result shows that the shearing rate will directly influence the strength index of direct shear consolidation fast shear test.
