基于稳定坡比计算的崩岸预警评估方法研究
Research on bank collapse early warning and assessment method based on stable slope ratio calculation
摘要
Abstract
To address current issues in bank collapse monitoring and early warning,such as poor timeliness and limited techni-cal approaches,and to enhance the capacity for pre-disaster prevention and emergency response,this study took the newly constructed bank section in Fengtai along the Anhui section of the Huaihe River as a case study.By comprehensively consider-ing the current conditions and future development trends of the riverbank,a bank collapse early warning and assessment method based on stable slope ratio calculation was established.Based on the comparison of stable slope ratio and predicted slope ratio,the river section was preliminarily divided into blue stable bank section,orange warning bank section,and red dan-gerous bank section.By incorporating river regime evolution and the potential disaster losses caused by bank collapse,the early warning levels were adjusted,and the riverbank collapse risk levels for different river sections were classified,leading to the development of a riverbank collapse early warning zoning map.For this section,a stable slope ratio of 0.25 was adopted,indi-cating a high likelihood of bank collapse in the near future,and it was designated as a red danger zone.The results could pro-vide technical support for enhancing pre-disaster prevention and emergency response capabilities for bank collapse.To provide a demonstration role for the stability evaluation of the Huaihe River beach,and to provide technical support for the competent authorities to improve their pre disaster prevention and emergency response capabilities.关键词
