复合土钉墙在某基坑支护结构中的应用

The Application of Composite Soil Nailing Walls in a Deep Foundation Pit

结合广州某深基坑工程实例,从分析基坑工程地质条件和场地周边环境入手,提出了复合土钉支护技术的设计方法,制定施工方案,并对该工程施工中出现的特殊情况进行分析和处理,基坑现场监测结果验证了复合土钉支护结构在基坑支护中的实用性.

On the base of a deep foundation pit in Guangzhou, through analyzing engineering geological conditions and venues surrounding the environment, it proposes the design method of composite soil nailing walls and construction program. At the same time,it suggests ways to handle the special circumstances during the construction period,and analyses the causes. The excavation site monitoring results verify the practicality of composite soil nailing in the pit maintenance.
