摘　　要：在建筑工程施工中,土体本身剪切强度低、抗拉强度低,而土钉挂网锚喷支护技术能够向土体中添加一定量的锚固体,具有“约束骨架”与“群体效应”,可有效地弥补土体本身强度不足,从而极大地提升边坡的整体刚性与稳定性。对此,研究结合具体工程案例,对地质复杂深基坑支护工程中运用土钉挂网锚喷支护技术的实践要点进行分析,以期为相关人员提供一定的参考和借鉴。In the construction of construction projects,the soil itself has low Shear strength and low tensile strength,while the soil nailing,mesh hanging,bolting and shotcreting support technology can add a certain amount of anchor solids to the soil,which has“constraint skeleton”and“group effect”,can effectively make up for the lack of strength of the soil itself,thus greatly improving the overall rigidity and stability of the slope.In this regard,this article combines specific engineering cases to analyze the practical key points of using soil nail hanging net anchor spraying support technology in geological complex deep foundation pit support engineering,in order to provide certain reference and reference for relevant personnel.
