Due to the high water level caused by the cascade construction along the river or the low standard of the built embankment in the original city，the current levee standards often fail to meet the requirements of the specifications and need to be heightened. Taking the design of Huangqiba protection dike in Minjiang River as an example，this paper puts forward several new types of flood control wall structure，and compares and analyzes their advantages and disadvantages. According to the structural characteristics of different flood control walls，the applicability of the new type of flood control wall in mountainous rivers and urban embankments is demonstrated.
