基于柔性复合材料面层的土钉墙支护应用研究

Application Research of Soil Nailing Wall Support Based on Flexible Composites Surface

为解决钢筋混凝土面层土钉墙支护工期长、效益低、环境影响大等问题,对柔性复合材料面层土钉墙支护体系在实际工程中的应用进行了探讨。介绍了柔性复合材料支护结构的基本组成和原理,在实际项目应用中对结构稳定性、支护效果、支护效益等方面进行了验算和分析。该柔性复合材料支护结构能够满足基坑工程的技术要求,可以在一定条件下替代混凝土面层支护,具有施工简单、成本低廉、无需大型设备等优势,值得类似工程借鉴。

In order to solve the current problems of reinforced concrete surface soil nailing wall support such as long construction period,low efficiency and large environmental impact,the application of flexible composites surface soil nail wall support system in actual engineering was discussed.The basic composition and principles of flexible composites support structure were introduced,the structural stability,support ef⁃fects,support benefits and other aspects were checked and analyzed in actual project applications.This flex⁃ible compositessupporting structure can meet the technical requirements of foundation pit project and can replace concrete surface support under certain conditions,has the advantages of simple construction,low cost,and no need for large equipment,and is worthy of reference for similar projects.
