河岸稳定性监测分析与评估方法Analysis and Evaluation Method of Riverbank Stability Monitoring

技术领域 technical field

本发明涉及水利工程技术领域,具体是一种河岸稳定性监测分析与评估方法。The invention relates to the technical field of water conservancy engineering, in particular to a method for monitoring, analyzing and evaluating river bank stability.

背景技术 Background technique

崩岸是河道演变的一种表现形式,普遍存在于冲积平原河道中,河岸线崩塌的影响不仅只是相关地段滩地逐渐被“蚕食”消失,尤其重要的是崩岸危及建设在滩地上的堤防工程基础安全,进而威胁着堤防保护区的人们生命财产安全,影响着河道岸线资源开发利用、河道两岸水利设施的正常运用、以及堤防保护区社会经济的正常发展。河道护岸工程是维持或控制河道岸线稳定的一种有效措施,被广泛应用于冲积平原河道治理工程,同所有的建筑工程一样,河道护岸工程不是一劳永逸、也有其自然寿命,尤其是水下护岸工程,水毁破坏是影响河道护岸工程自然寿命的主要因素,失去护岸工程保护的岸坡距离发生崩岸的日子就不远了。Bank collapse is a manifestation of river channel evolution, which is commonly found in alluvial plain channels. The impact of bank collapse is not only that the beach in relevant areas is gradually "eroded" and disappears, but more importantly, bank collapse endangers the embankment projects built on the beach. Basic security, which in turn threatens the safety of people's lives and property in the embankment protection area, affects the development and utilization of river shoreline resources, the normal use of water conservancy facilities on both sides of the river, and the normal development of the social economy in the embankment protection area. River revetment engineering is an effective measure to maintain or control the stability of the river bank. It is widely used in alluvial plain river improvement projects. Like all construction projects, river revetment engineering is not once and for all, and has its natural life, especially underwater revetment Engineering, water damage is the main factor affecting the natural life of river revetment works, and the bank slopes that lose the protection of revetment works are not far from the day when bank collapse occurs.

The scale is much larger. The collapse of the river bank or the instability of the river bank is a process of continuous accumulation of river bank stability risks. It generally goes through the time process of the occurrence, cumulative development, and occurrence of bank stability risks. Prevention of unburned hazards, timely treatment of hidden dangers of river bank stability, has a significant effect on maintaining the stability of river banks, and can avoid major safety accidents such as flood control. Analyzing and evaluating the degree of river bank stability risk is an important basis for determining the treatment of river bank stability risk, and it has a guiding role in the flood control and rescue work of river courses.
