摘要

岩土热流耦合问题十分复杂

而离心机模型试验和有限元数值分析为研究这些问题提供了技术和方法。针对前人的土体热流耦合离心机试验

利用COMSOL多物理场有限元分析软件对饱和砂土中温度引起的自然对流及其相互影响进行分析。总结了传热和渗流下离心机模型与原型的相似法则

说明了自然对流在饱和土体传热中的重要性。分析表明

满足相似比尺的离心机试验和COMSOL数值模型均能正确模拟饱和土体中的热流耦合问题

土体渗透系数对饱和土体的传热有较大影响。

Abstract

The analyses of thermal-hydraulic coupling effects in geotechnical problems often present great complexity

but centrifuge test and finite element method can be of great help in these situations. This paper focuses on thermal-hydraulic coupled centrifuge tests and examines the free convection and thermal-hydraulic coupling phenomena in saturated sand via COMSOL

the finite element software of multiphysics. Besides

the scaling laws of centrifuge model test in saturated soil are summarized and the significance of free convection in heat transfer is revealed. The results show that centrifuge tests and numerical experiments which satisfy the scaling laws can properly simulate the thermal-hydraulic coupling effects in saturated soil and that the permeability coefficient has a significant effect on heat transfer in saturated soils.
