运用PFC3D软件建立了砂浆离散模型，通过控制变量法分析了模型接触参数对砂浆宏观流变参数（剪切屈服值）的影响，建立了两者之间的定量关系，同时对新拌砂浆进行了流动度试验，通过分析试验与数值模拟结果，验证了离散模型及模型接触参数与剪切屈服值定量关系的正确性。

The paper establishes discrete mortar model by applying PFC3D software,analyzes the impact of mortar contact parameters upon mac-ro-mortar fluidity parameter( shear yield value)by controlling variable method,establishes their quantitative relationship,carries out fluidity test for fresh mortar,compares experimental results to numerical simulation results,and finally testifies the quantitative relationship correctness of dis-crete element model and model contact parameter and shear yield value.
