摘　　要：在深基坑工程施工过程中,需要将原有支撑体系拆除,为了确保整个基坑工程安全的开展,在支撑体系拆除之后,需要采取相应的换撑措施,将因支撑体系拆除而产生的荷载进行转移,由第三者来承担这部分荷载。但在实际开展过程中,换撑施工具有一定的缺陷,如整体性较差、施工效率低等。本文将在现有换撑技术的基础上,通过对传统换撑技术的研究,从传统换撑施工中存在的问题出发,对传统换撑技术进行改进,从而推进换撑技术的发展。In the construction of deep foundation pit, the supporting system needs to be dismantled. In order to ensure the safety of the whole foundation pit, after the demolition of the supporting system, corresponding replacing measures need to be taken to transfer the load generated by the demolition of the supporting system to the third structure. However, in the practical engineering, there are some defects during the process of replacement of support, such as poor integrity and low efficiency. Based on the existing support replacing technology, this paper studies the traditional support replacing technology, analyzes the existing problems and proposes to improve the traditional technology to promote the development of the support replacing technology.
