摘要
采用直升导管法进行水下（泥浆下）灌注施工时，确定灌注工艺参数的难点是如何确定砼在环空中的流动阻力，砼在环空中的流动阻力可以通过室内模拟实验结合施工现场的实测来确定；本文拟应用流体力学和砼的流变特性的原理，从理论上探讨砼在环空中流动阻力的计算方法。
Under construction of grouting underwater(undermud)by conduct, the difficulty to determine the technological param eter of grouting is how to decide the flow resistance of concrete in circumair, which can be defined by indoor simulated test and combining with practical survey on worksites. In this paper, the author uses the fundamentals of hydromechanics and concrete rheologic feature to study the methods for calculating the flow resistance of concrete in circumair.
