摘要:
通过设计不同配合比的减摩泥浆进行泥浆性能试验，得到膨润土和聚丙烯酰胺对泥浆性能的影响规律，结合城市主干道路交叉口超大断面矩形顶管工程，进行泥浆配合比优化和减摩效果测试模型试验，得到适合场地土层特性的优化配合比的减摩泥浆，实验结果表明，在饱和软土中注入优化配合比的减摩泥浆可将摩擦力降低至原来的55.7%，在饱和砂土中可将摩擦力降低至原来的63.1%，研究成果将为今后大断面顶管工程减摩注浆提供理论基础和借鉴作用。
Abstract:
The slurry performance tests were carried out by designing anti-friction slurries with different mix ratios, and the effects of bentonite and poly-acrylamide on slurry performance were obtained. Then, combined with the large section rectangular pipe jacking project at the intersection of an urban main road, the optimization of slurry mix ratio and the model tests of their anti-friction effects were carried out, and the optimum mix ratio suitable for the soil layer characteristics of the site was obtained. Test results show that injecting anti-friction slurry with an optimized mix ratio into saturated soft soil can reduce the friction by about 44.3%, and injecting it into saturated sand can reduce the friction by 36.9%. The research results will provide theoretical basis and reference for future large-section pipe jacking engineering.
