摘　　要：高层建筑深基坑选择三轴搅拌桩支护、混凝土灌注桩支护等多结构形式相结合的方式进行施工。在施工过程中,对深层土体水平位移、沉降、周边建筑物等进行实时监测。深基坑支护施工时,不仅要确保基坑内作业的安全性,还需避免基坑、坑外土体出现移动现象。同时,还要避免对基坑周围建筑物、道路和管线等产生影响。文章通过对该工程所采用的深基坑支护技术进行分析和实践,发现其具有一定的发展前景,值得推广和应用。The deep foundation pit of high-rise buildings is constructed by a combination of three axis mixing pile support and concrete pouring pile support structure.During the construction process,real-time monitoring is carried out on the horizontal displacement,settlement,and surrounding buildings of deep soil.During the construction of deep foundation pit support,it is not only necessary to ensure the safety of the operation inside the foundation pit,but also to avoid the movement of the foundation pit and the soil outside the pit.At the same time,it is also necessary to avoid any impact on the surrounding buildings,roads,and pipelines of the foundation pit.Through analysis and practice of the deep foundation pit support technology used in this paper,it is found that it has certain development prospects and is worth promoting and applying.
