mIn the project of casting yard for tunnel elements in Guishan of Hongkong-Zhuhai-Macao Bridge, the huge size offloating gate and its large hydraulic pressure have brought a great challenge to the design of base plate of dock entrance. Wedesigned one new type of base plate of dock entrance with functions of guidance and supporting after a series of studies. Weintroduced the new-type base plate structure of the dock entrance, and focus on the key technologies such as design concept,design method and structural properties. The structure has played a good role in the operation of the casting yard, andeffectively guaranteed the installing precision and steadiness of floating gate during its operation.
