【摘要】 文献检索表明:目前国内外还没有一个能较准确计算宾汉姆流体以柱面渗透注浆形式的扩散半径理论公式。文章以宾汉姆流体流变方程及渗流运动方程为基础,推导了柱面渗透注浆形式的宾汉姆流体扩散半径理论公式;分析了宾汉姆流体流变性、注浆压力、地下水压力及配置流体的水体温度对柱面渗透注浆形式的扩散半径的影响;设计注浆试验对其进行验证。结果表明:由柱面渗透注浆形式的宾汉姆流体扩散半径理论公式计算出的扩散半径理论值与注浆试验的实测值两者间,虽有30%左右的差异,但都处于可接受误差范围内。因此,研究成果可为实际注浆施工提供理论支撑与指导作用。更多还原

【Abstract】 At present it is a blank for a theoretical calculation formula for diffusion radius of Bingham fluid based on column penetration grouting both at home and abroad.In this paper,a theory formula in this regard was deduced according to rheological equation and seepage motion equation of Bingham fluid.The influences of Bingham fluid rheological behavior,grouting pressure,groundwater pressure and water temperature of prepared grout on diffusion radius based on column penetration grouting are theoretically analyzed and then verified by grouting test.Results show that though there is 30% differences between calculated theoretical values and measured values in grouting tests,they are still within the range of acceptable errors.Therefore,the research findings provide theoretical support and play a guiding role in the process of grouting.更多还原
