摘要
介绍了在地铁深基坑施工中采取预应力锚索支护的成功经验,通过对锚索施工方案的比选及相关参数的优化,起到了降低施工难度,确保施工质量的作用,同时对预应力损失也做了较为详细的分析,从而保证了锚索施工质量符合设计要求。
Successful experience about prestressed cables support in deep excavation is introduced in this paper.Construction difficulty has been reduced and the corresponding quality of construction has been assured through the comparison of consruction schemes and optimization of relevant parameters.A more detailed analysis is done to the prestress loss of prestressed cables,thus,it ensures that the construction quality of cable meets the design requirement.
