喀斯特地貌区建筑固废填方市政广场变形监测

Deformation Monitoring of ConstructionSolid Waste Filling Municipal Square in Karst Landform Area

为应对建筑固废污染及天然砂石等建筑材料短缺和建筑全过程能耗量滞后绿色建筑方针,同时喀斯特石漠化山区城市填方广场建设工程可消耗大量建筑固废助力双碳目标。基于此,实施了以山区城市填方市政广场为背景及载体进行建筑固废资源化再开发利用再建设。鉴于主要以地形地貌与地层岩性,建筑固废覆填混合料特性为表现的新复杂环境工况,重点对建筑固废覆填挖填方广场地表沉降,变形滑坡及支挡结构进行了变形自动监测和结果分析,得出的一系列结论和经验可为将来类似工程建设提供参考。

In order to deal with the pollution of building solid waste and the shortage of building materials such as natural sand-gravel,and the energy consumption of the whole building process lags behind the green building policy.At the same time,the construction project of urban filling square in karst rocky desertification mountainous area can consume a large amount of building solid waste to help the dual carbon target.Based on this,the redevelopment and utilization of construction solid waste resources were carried out with the background and carrier of the filling municipal square in mountainous cities.In view of the new complex engineeringenvironmental conditions,which are mainly characterized by topography and lithology,and the characteristics of construction solid waste filling mixture.The surface subsidence,deformation landslide and retaining structure of the construction solid waste filling square aremainly monitoredautomatically,and a series of conclusions and experiences are drawn,which can provide reference for similar projects in the future.
