非承重包裹式加筋土桥台工作机理监测方案研究

Monitoring a Non-Load-Bearing Wrapped Geosynthetics Reinforced Soil Abutment

非承重式加筋土桥台相较传统桥台具有桥梁减锥坡跨、改善台背回填性能、快速建造和桥梁景观提升的优势,在当前用地紧张、装配化施工、生态减碳大背景下有非常好的应用和推广价值。结合明巢高速包裹式非承重加筋土桥台试验工程的监测实践,详细介绍了试验工程的监测目的、内容和监测元器件的选择,总结了现场监测实施情况和注意事项。现场监测对包裹式加筋土桥台工作机理研究及服役性能验证具有重要意义,也为类似工程的监测方案制定和实施提供借鉴。

Compared with the traditional abutments, the mixed abutment has the advantages of reducing the span length of the bridge superstructure, improving the backfill performance, rapid construction and improving the bridge esthetics. The structure has very good applications and promotion values under the current background of land shortage, assembly construction and ecological carbon reduction. Based on the monitoring practice of the wrapped non-load-bearing reinforced soil abutments in Mingguang to Chaohu Expressway Project, this paper introduces the details of monitoring purpose, content and selection of monitoring components of the project, also summarizes the implementation and potential critical aspects for the field monitoring. The field monitoring is of great significance to the study of working mechanism and service performance of the wrapped geosynthetic reinforced soil abutment.
