摘要
结合工程实例,介绍了预应力鱼腹梁式钢支撑和旋喷搅拌加劲桩在深基坑支护结构中的综合应用,并探讨了其工作机理和技术特点。工程实践结果表明,这两种较新的基坑支护锚固技术在基坑安全性、造价和方便施工等方面均有优势。
Based on the engineering practice, this paper introduced the application of the prestressed fishbellied beam steel shoring and the rotary jet mixing anchor piles in the retaining structures of deep foundation excavation. The mechanism and technique features were investigated. The engineering practice shows that the new technologies have advantages in foundation excavation safety, cost and convenience of construction, etc.
