桥梁桩墩式基础加固处理关键技术研究
|
摘要
以成都地铁18号线火车南站车站基坑工程为例,对开挖施工过程中既有桩基加固处理方案进行分析,重点阐述了加固的技术措施,通过对沉降监测数据分析,得知该加固技术合理有效,以期对工程施工有所帮助。
Taking the foundation pit project of south railway station of Chengdu metro line 18 as an example,this paper analyzes the treatment scheme of existing pile foundation reinforcement during excavation construction,and mainly expounds the technical measures of reinforcement.Through the analysis of settlement monitoring data,it is found that the reinforcement technology is reasonable and effective,so as to be helpful to the construction of the project.
