摘　　要：顺逆结合施工技术是针对基坑工程的一种作业模式,其以周边逐层顺逆结合式强化支撑组合与逆作楼板的结合程度,为基坑提供有效的支护体系,来满足基坑施工作业的相应要求。顺逆结合施工技术需要精准的施工组织与协调,在保证地下结构高精度施工的同时消除土方开挖与结构施工、基坑支护的相互影响,因此受到工程界的广泛关注。本文以佛山国际金融中心工程为例,结合项目特点及要求,在基坑周边区域进行了顺逆结合施工工艺的原理分析和专项设计,通过对项目边坡监控数据分析可知:在地下结构顺逆结合施工的特定期间,基坑支护桩体的水平位移数据呈现出极为稳定的状态,始终保持在设计要求的范围之内,未出现超出设计标准的波动情况。本项目地下工程所采用的顺逆结合施工方案可以有效提高施工安全性,缩短工期,同时降低施工成本。研究成果为顺逆结合技术在超高层结构地下工程施工中的推广应用提供了理论依据。The obverse and reverse construction technology is a mode of operation for foundation pit engineering.It strengthens the combination of support and reverse floor slabs layer by layer around the perimeter,providing an effective support system for the foundation pit to meet the corresponding requirements of foundation pit construction operations.The obverse and reverse construction technology,which requires precise construction organization and coordination,ensures high-precision construction of underground structures while eliminating the mutual influence of earthwork excavation and structural construction,foundation pit support.Therefore,it has attracted widespread attention in the engineering field.This paper takes the Foshan International Financial Center Project as an example,combining the characteristics and requirements of the project,analyzes the principle and carries out special design of the obverse and reverse construction technology in the area around the foundation pit.Through the analysis of the project slope monitoring data,it is found that during the specific period of obverse and reverse construction of the underground structure,the horizontal displacement data of the foundation pit support piles remain very stable,always within the range required by the design,and no fluctuations beyond the design standards have occurred.The obverse and reverse construction schemes adopted in the underground engineering of this project can effectively improve construction safety,shorten the construction period,and reduce construction costs.The research results provide a theoretical basis for the promotion and application of obverse and reverse construction technology in the underground engineering of super high-rise structures.
