拉锚支护结构在北方砂土地层基坑工程中的应用

The Application of Anchor Support Structure in Foundation Pit Engineering of Northern Sandy Soil Stratum

随着我国“一带一路”国家战略的不断发展,以及我国基础建设的高速发展,必然进一步推动我国城市现代化建设。城市地下空间的不断开发与利用,基坑工程也朝着周边环境越来越复杂及开挖深度越来越深的方向发展,必然给基坑工程支护技术的发展带来新的挑战。通过北方砂土地层基坑工程实例介绍了拉锚支护结构在基坑支护中的应用,以吉林砂土地区某深基坑工程为研究背景,分析基坑工程设计与施工,为该地区类似基坑工程设计及该地区砂土地层类似基坑工程的安全施工提供参考。

With the continuous development of China s“The Belt,thr Road”national strategy and the rapid development of China s infrastructure construction,China s urban modernization will inevitably be further promoted.With the continuous development and utilization of urban underground space,the foundation pit engineering is also developing towards the increasingly complex surrounding environment and the deepening of the excavation depth,which will inevitably bring new challenges to the development of foundation pit supporting technology.This paper introduces the application of the anchor support structure in the foundation pit support with the example of the foundation pit engineering in the northern sandy stratum.Taking the deep foundation pit engineering in the sandy area of Jilin city as the research background,the foundation pit engineering design and construction are analyzed,which provides first-hand information for the similar foundation pit engineering design,and can be used as the good reference for the safe construction of similar foundation pits engineering in the sandy stratum of the area.
