基于预应力锚索施工工艺,并结合海南海口塔基坑场地地质条件复杂及周边环境对变形敏感等客观情况,对预应力锚索从施工准备到张拉锁定进行了全过程的梳理。分析了各工序的相关施工影响因素,总结了施工技术控制要点。
Based on the prestressed anchor cable construction process, combined with the complex geological conditions in the base of pit excavation in Haikou, Hainan Province, and the sensitivity of the surrounding environment to deformation, the whole process of prestressed anchorage cables from construction preparation to tension locking was investigated. The influencing factors of construction related to each process are analyzed, and the key points of construction technology control are summarized.
