【摘要】 为解决砂质海堤因面板伸缩缝破损导致的砂土流失问题，本文通过单轴压缩试验、细观结构分析及波浪水槽模型试验，系统研究了低胶凝掺量胶结砂的力学特性与防治效果。通过模型试验，验证了采用低胶凝掺量胶结砂处理伸缩缝破损可有效控制砂土流失，证明该材料是一种经济有效的海堤砂土流失防治材料。研究成果为该类材料在海堤工程中的应用提供了关键依据。更多还原

【Abstract】 To address the issue of sand loss caused by the damage of expansion joints on the panels of sandy seawall, this paper systematically studies the mechanical properties and prevention and control effects of low-cement-content cemented sand through uniaxial compression tests, mesoscopic structural analysis and wave trough model tests. Through model tests, it was verified that treating the damaged expansion joints of seawall panels with low-cementitious content cemented sand can effectively control the loss of sand and soil, proving that this material is an economical and effective material for preventing the loss of sand and soil in seawall. The research results provide a key basis for the application of this type of material in seawall projects.更多还原
