本文介绍了鄂东长江大桥主4号墩钻孔平台的设计及施工方案,设计中选用钢护筒作为受力基础,选用型钢作为上部分配梁,采用MIDAS有限元建模软件对各受力杆件强度及稳定性在最不利工况下分别做出了验算。同时也考虑了大型临时施工设施的经济性、适用性及安全性等方面。
This paper introduces the design and construction scheme of drilling platform of Pier No.4 of the East Hubei Yangtze River Bridge. The steel casing is chosen as the foundation of the force and the section steel is selected as the upper distribution beam. The finite element modeling software MIDAS Pieces of strength and stability in the most adverse conditions have made a check. At the same time, the economy, applicability and safety of large-scale temporary construction facilities have also been considered.
