摘　　要：随着城市交通的发展，在管棚内顶进箱涵工程变得愈加重要，而目前的施工工艺不可避免对土体产生扰动，从而产生沉降，针对此问题进行分析，提出在管棚内顶箱涵顶进对地表变形的影响因素及控制方法。With the development of transportation, the culvert box advancing within a pipe shed becomes more and more important, but the present construction method is inevitable to move the soil, thereby produces settlement. The main body of this paper is the analysis of this problem, and indicates the factor of the box culvert advancing forward to the ground settlement and how to control it.
