梯形复合衬砌渠道冻胀破坏力学模型研究
Research of Mechanics Models of Frost Heaving Damage of Composite Lining Trapezoidal Canal
摘要
Abstract
The composite lining seepage control canals combined with compound geomenbrane and concrete plate are widely used in recent years. As a kind of seepage control material which is thin,continuity and soft,the research of seepage control characteristics of compound geomenbrane has obtained many achievements. But the mechanics characteristics of the composite lining canals also lack of research. In this paper,the mechanics models of frost heaving damage of composite lining canal combined with compound geomenbrane and concrete plate were established for the trape-zoidal section canal,the internal force of the lining plates are solved and the thickness of the concrete plates were checked. The influencing factors of frost heaving damage of composite lining trapezoidal canal were analyzed. The results indicate that the tangential force of constraint of the lining plate is decreased by augment composite geomembrane. So it can play the role of anti-freezing expansion damage.关键词
