基于地球物理探测的海塘结构隐患与地质环境关联性分析——以上海典型岸段为例OA

This study focuses on typical sections of Shanghai's first-tier seawalls as the research object,employing both ground-penetrating radar and seismic imaging for comprehensive hazard detection of the foundational structures across multiple seawall sections.It systematically analyzes the distribution characteristics of hazards,proposes a hazard assessment factor to characterize the degree of hazard development,and compares the hazard detection results with geological environmental backgrounds such as seawall settlement and coastal erosion.Geophysical methods can effectively identify internal hazards within seawall structures,with hazard development exhibiting distinct spatial patterns that can be quantified using the hazard assessment factor.The distribution of seawall hazards shows an overall positive correlation with geological environmental monitoring results such as settlement and coastal erosion,indicating that hazards are more developed in areas with poorer geological environmental background stability.However,localized discrepancies exist that deviate from this trend,which are speculated to be related to the influence of human activities.
