胶凝砂砾石材料在防冲结构中的应用

Application of cemented sand gravel material in anti-scour structure

在防洪堤结构中,护脚的抗冲防护作用至关重要,持久耐用、防护效果好的护脚结构能为防洪堤结构提供有效、可靠的保护。结合犍为航电枢纽前丰坝堤防工程,引入胶凝砂砾石新型材料作为新的防冲结构材料。对不同的护脚形式从适用性、耐久性、造价等方面进行对比分析,探讨胶凝砂砾石预制四面体护脚在堤防工程、河道防冲等结构中的运用。

In the flood protection dike,the impact protection of the foot protection structure is very important.The durable foot protection structure with good protection effect can provide effective and reliable protection for the flood dike structure.In this paper,combined with Qianfengba dike project of Qianwei navigation power junction,a new type of cemented sand gravel material is introduced as a new anti-scour structural material.The applicability,durability and cost of different types of foot protection are compared and analyzed,the application of prefabricated tetrahedral toe protection of cemented sand gravel in dike engineering and river anti-scour structure is discussed.
