摘　　要：对聚合物稳定剂水泥浆和膨润土稳定剂水泥浆进行了流变性试验研究,按宾汉流变模型对其流变参数进行了理论计算;研究结果表明,聚合物稳定剂水泥浆动切应力较膨润土稳定剂水泥浆低,其浆液的可灌性和扩展半径要优于膨润土稳定剂水泥浆,可成为GIN灌浆法中优良的稳定水泥浆液,该项研究具有很强的工程实用价值。The test study on the rheologicul property of polymer-stabilizer-cement paste and expansive soil-stabilizer-cement paste is carried out, and the theoretical calculation of the rheological coefficient is performed based on the Binham Fluid Model. The research results demonstrate that the dynamic tangential stress of the polymer-stabilizer cement paste is smaller than that of the expansive soil stabilizer cement paste. The groutability and extending radius of the former are better than those of the later. The polymer-stability-cement paste can be used as an excellent stable grouting liquid in GIN grouting method. This polymer-stabilizer-cement paste is potential in engineering practice in future.
