摘要
甘肃省人民医院7#楼、8#楼在深基坑支护降水过程中采用咬合桩+预应力锚索,通过导板定位、咬合桩硬切割和测斜技术应用,保证了饱和砂岩层深基坑施工安全,提高了经济效益和社会效益,可为同类项目提供借鉴。
The 7#and 8#buildings of the People's Hospital of Gansu Province used occlusal piles+prestressed anchor cables in the process of deep foundation pit support and dewatering,which guaranteed the safety of deep foundation pit construction in saturated sandstone layer through guide plate positioning,hard cutting of occlusal piles and application of inclinometer technology,improved economic and social benefits,and could provide reference for similar projects.
