Abstract

Research background: In recent years, with the continuous occurrence of extreme rainfall, excessive concentration of rainfall occurred from time to time, and dike breach was one of the most harmful disasters in flood disasters. For example, in July 2024, a dike breach occurred in TuanzhouDongting Lake, Huarong County, Yueyang, Hunan Province, and a dike breach occurred in Xiangtan County, Hunan Province, On August 10, 2023, the dike on the east side of Tanli Trunk Canal in Tanli Town, Wen’an County, Hebei Province, upstream of the Daqing River, broke.

Purpose and significance: every breach in embankment engineering poses a serious threat to the safety of people’s lives and property, so it is of great significance to conduct research on quickly and effectively sealing embankment breaches. Traditional methods of sealing breaches mostly use throwing stones, but the stones are limited by their weight and shape, and are washed away by the water flow before stabilizing on the riverbed, making it difficult to effectively seal breaches. Therefore, traditional throwing stone sealing methods are often difficult to succeed at breaches with turbulent water flow. This article explores the application of steel sheet piles from the perspective of sealing gaps, analyzes and summarizes the construction process and technology of Larson IV steel sheet piles in sealing gaps, and establishes finite element models based on different sealing schemes to calculate and analyze performance indicators such as strength, stiffness, and stability. Due to the strong anchoring force of soil on steel sheet piles, the success rate of sealing is greatly improved compared to stone throwing sealing, and the sealing time is significantly saved. The calculation results show that using steel sheet pile enclosure structure to seal embankment breaches is completely feasible.
