摘要
随着我国水利工程建设的飞速发展,形成了大量新河岸,新河岸土体极易被水流冲蚀流失,诱发地质灾害,对人民的生命财产安全造成严重威胁。本文通过ABAQUS分析水流冲蚀作用下粘性土河岸边坡稳定性随时间的变化规律,发现河岸边坡的稳定系数随着水流冲蚀时间而下降;随着冲蚀时间的推移,河岸边坡稳定系数下降明显加快。本文通过水流冲蚀作用下河岸边坡稳定性研究将对河岸边坡的防护与监测起到现实的指导意义。
With the rapid development of the construction of water conservancy projects in China, a large number of new river banks have been formed. The new river bank soil is easily eroded by water flow, causing geological disasters and posing a serious threat to the safety of people’s lives and property. In this paper, the ABAQUS is used to analyze the change law of the stability of the river bank slope under the action of water erosion, and it is found that the stability coefficient of the river bank slope decreases with the current erosion time;as the erosion time passes, the decline in the stability coefficient of the river bank slope has accelerated significantly. In this paper, the study on the stability of river bank slopes under the action of water flow erosion will have a practical guiding significance for the protection and monitoring of river bank slopes.
