摘要
驳岸作为沿河地面以下保护河岸的建(构)筑物,也是河道发挥功能的重要支撑,其稳定性直接影响着城市内河岸坡的安全。福州内河众多,受台风暴雨、内河引水,以及城市环境等复杂的水文和环境影响,近年驳岸出现失稳现象时有发生。以福州光明港驳岸为例,通过河道清淤深度、内河水位变化幅度、驳岸挡土墙墙顶堆载高度等条件的调查,分析各主要因素对驳岸稳定性的影响,通过建立驳岸地质模型,采用极限平衡法以及有限元法定量评价驳岸的稳定性,确定稳定性评价标准。研究成果可为城市内河驳岸的稳定性风险评价及加固提供依据。
As a building(structure)that protects the riverbank below the ground along the river,the revetment is also an important support for the river to function,and the city river’s bank slope is safeguarded by its stability.There are many inland rivers in Fuzhou,and the instability of the revetment has occurred in recent years due to the complex hydrological and environmental influences such as typhoon and rainstorm,inland water diversion,and urban environment.In this paper,the influence of main factors on the stability of the revetments is analyzed by investigating the depth of river dredging,the variation of the inland water level,and the height of stacking on top of the revetment retaining wall and establish a geological model of revetments.The results of the study can provide a basis for the stability risk evaluation and the improvement of the revetments in urban inland rivers.
