钻孔桩水下灌注混凝土流动规律理论研究

THE THEORETIC STUDY ABOUT LAW OF THE UNDERWATER POURING CONCRETE IN THE DRILLING PILE

运用流体力学有关理论,对水下灌注混凝土流动的流态模型进行理论研究,提出了两种水下混凝土流动的力学模型,一种是应用渗透理论建立的渗流模型;另一种是应用射流理论建立的湍流K-ε模型。将两种渗模型进行对比分析和探讨,论证利用该模型进行数值模拟的可行性和优越性。

Some theory of fluid mechanics is applied to analysis on the circulating law of the underwater concrete, and two mechanic models are put forward, one is the seepage model according to the seepage theory, the other is the turbulent flow K -ε model. The two models are analyzed on and discussed by contrast, the feasibility and advantage of it are demonstrated.
