摘　　要：新建妫水河铁路特大桥位于塞北官厅水库中，常年冬季结冰厚４０～６０ｃｍ。在建桥过程中，栈桥和钻机平台桩基、钢护筒、双壁钢围堰等大临设施采用活水圈、人工破冰、破冰船破冰及吊挂软物体等方法消除了静冰压力，利用爆破法破冰，消除了动冰的撞击力。该方法简单易行，可供借鉴。The newly built Guishui River Railway Bridge is at Gongting resevoir,it is usually freezing ice 40-60 cm thick in winter.During the construction ,in order to protect the large interim services such as trestle bridge,steel protective casing and double-walled steel cofferdam,static ice pressure and dynamic percussive force were eliminated from water by use of various methods.The methods are simple and practical,which could offer the reader some references.
