海堤工程病害分析与除险设计研究

Disease Analysis and Risk Elimination Design of Seawall Engineering

摘要:

在多年潮流和风浪的作用下，海堤结构部分区域受到了不同程度的损坏或影响。海堤多处的表观损坏本身对海堤防潮安全并不造成较大影响，但形成原因均与海堤堤身变形引起的不均匀沉降有关。通过对大堤现场观测和检测，初步探明海堤病害情况。根据综合分析与复核，对病害成因进一步探究，查明病害形成机理和大堤主要安全隐患。制定针对性的除险加固方案，消除安全隐患。相关经验为类似海堤工程病害分析与除险设计提供参考。

Abstract:

Under the action of tides and wind waves for many years, some zones of the seawall structure have been damaged or affected to varying degrees. The superficial damage in many places of the seawall itself does not have a major impact on the tide-proof safety of the seawall, but the causes are related to the uneven settlement caused by the deformation of the seawall body. Through on-site observation and testing of the levee, the disease situation of the seawall has been preliminarily explored. Based on comprehensive analysis and recheck, the causes of the disease are further explored to identify the disease formation mechanism and the main safety hazards of the levee. The targeted risk elimination and reinforcement schemes are developed to eliminate the potential safety hazards, which provides the reference for the disease analysis and risk elimination design of similar seawall engineering.
