对国内外常用的几种流变模式进行了分析和评价,指出了它们的特点和不足之处。在总结和归纳的基础上,提出了一个带静切应力的三参数多项幂律模式(简称L—M模式)。研究还从该模式的本构方程出发,推导出流变参数及有关水力参数计算式,并应用大量的泥浆及水泥浆试验资料和计算数据,对比和分析了各流变模式的适应范围及精确程度,进而证明了L—M、H—B流变模式具有适应范围广、准确性高的特点。
Several rheological models commonly used at home and abroad are analyzed and evaluated, and their characteristics and shortcomings are pointed out. On the basis of summarizing and summarizing, a three-parameter multinomial power law model with static stress (L-M mode) is proposed. Based on the constitutive equation of the model, the rheological parameters and formulas for calculation of hydraulic parameters are also deduced. The experimental data and calculated data of slurry and grout are also used to compare and analyze the adaptability and accuracy of each rheological model Which proves that L-M and H-B rheological models have a wide range of adaptability and high accuracy.
