干旱气候下高液限黏土质堤防裂隙演变分析
Analysis of crack evolution in high liquid limit clay embankment under arid climate
摘要
Abstract
With the intensification of global climate change,the frequency of extreme arid climate in the world is gradually in-creasing.The arid climate could cause the high liquid limit clay embankments to shrink and produce cracks.Under indoor sim-ilarity test,digital image processing technology and numerical simulation,the fracture development law of high liquid limit clay embankment in Huaibei embankment was studied.The results showed that digital image processing technology could efficiently and accurately identify the cracks on the surface of the sample,which is helpful to analyze the trend of crack development.During the drying process,the development process of fracture degree at the top of the embankment can be divided into three stages,which are slow development stage,rapid development stage and stable development stage.Uneven solar radiation inten-sity exacerbates the development of cracks at the top of the embankment.关键词
