Abstract: 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.
