应用砼的流变性计算砼的灌注参数

Grouting Parameters Determined by Concrete Rheology

摘要:

应用流体力学、流变学的理论、方法和施工实测数据，建立水下灌注砼时导管埋深、砼在灌注系统的流动阻力与导管内附加砼柱间的数学表达式，以指导水下灌注施工在最优灌注参数下进行。

Abstract:

Based on fluid mechanics, rheologic theory, method, and field data, a mathematic expressions was formed for burial depth of the underwater grouting tremie and the relationship between flow resistance of the concrete in the grouting system and theadditional concrete head are established to guide underwater grouting to be carried out by optimum grouting parameters.
