广州某地铁站配合外界荷载变化引起的复杂工况结构设计

广州某地铁站在主体结构施工过程中,由于外部盾构施工荷载的改变,使得车站主体结构在原设计状态下无法承受施工荷载,且不具备盾构施工条件,在此条件下,通过简单有效的加强设计,最终保证了盾构施工顺利和车站结构安全。

The Structural Design to Cooperate the External Load Changed with Complex Working Condition of the Guangzhou Subway Station

During the major structure process of Guangzhou subway station,the external load changed owing to the tunnel shield constructed,the major structure of the subway station could not carry the load on the initial design situation.And the subway station did not have the condition to keep on constructing the tunnel shield.In this condition,this paper used the simple and effective method to enhance the design of the major structure during construction,ensured the smooth construction of the tunnel shield and the safety of the subway station structure.
