| Abstract: | The paper introduces the general structure and operational principle of the self-travelling shuttering system for the northern bridge approach. In terms of the characteristics of the high transverse stress level of the bottom slab of cantilever box girders, the authors analysed especially the main points of the linear control of the bottom slabs of box girders and the characteristics of load bearing of the cantilever beam, explaining the causes and proposing the engineering measures for the construction of the bridge approach. |
