装配式锚拉型格栅生态挡墙的工程应用与监测分析

Engineering Application and Monitoring Analysis of Fabricated Anchor Type of Ecological Grid Retaining Wall

目前,挡墙多数为现浇结构,这类挡墙施工效率较低,扬尘也影响附近居民。因此,该文提出一种在预制场加工,到现场拼装且绿化能力佳的装配式锚拉型格栅生态挡墙。首先针对其结构特点进行施工技术研究;然后依托实际工程,采用自动化监测手段,对其地表位移、地表倾斜、深部位移、地下水位进行监测;最后利用有限元软件,验证监测的位移情况。研究结果表明,该边坡工点挡墙处于安全状态,有限元模拟的挡墙位移结果与监测位移结果基本吻合,可将其视作RTT位移模式。

At present,most of the retaining walls are cast-in-situ structures,which has low efficiency of construction and dust which affects nearby residents.Therefore,this paper proposes a fabricated anchor type of ecological grid retaining wall which is processed in the prefabrication yard,assembled on site with good greening capacity.Firstly,the construction technology is studied according to its structural charac-teristics.Then,depending on the practical project,the surface displacement,surface tilt,deep displace-ment and groundwater level are monitored by means of automatic monitoring.Finally,the finite element software is used to verify the monitored displacement.The research results show that the retaining wall of the slope construction site is in safety,and the displacement results of the retaining wall simulated by the finite element method are basically consistent with the monitoring displacement results,which can be re-garded as RTT displacement mode.
