中文摘要：
针对寒区结冰水域直立结构上的挤压冰力问题，利用渤海原型测量数据，证明了当直立结构上发生海冰挤压同时破坏时，基于挤压非同时破坏理论的“低值冰力”不再适用。基于对渤海原型测量数据的分析，并结合海冰的韧脆转变行为特性，讨论了直立结构上海冰挤压同时破坏的易发性，指出冰板与结构的全接触是海冰挤压同时破坏发生的关键条件，这种全接触要求可导致韧性或韧脆转变破坏的低冰速和不易导致破碎冰堆积和残留的柔性窄结构，即低冰速下的直立柔性窄结构极易发生海冰挤压同时破坏。
英文摘要：
With a focus on the crushing ice force on vertical structures in ice-infested waters and based on the field data from the Bohai Sea, simultaneous ice crushing failure has been identified and it has been proved that the ＂low level ice force＂ which is based on non-simultaneous ice crushing failure is not valid when simultaneous ice crushing failure arises on vertical structures. Based on the analysis of the field data from the Bohai Sea and the ductile to brittle transition behavior of the sea ice, the susceptibility of vertical structures to simultaneous ice crushing failure is discussed. The full contact between the undamaged ice edge and the structure is the key condition for simultaneous crushing failure of the ice sheet. The full contact requires low ice velocity which leads to the ductile or ductile to brittle transition failure of the sea ice and narrow and compliant structures which avoids the piling up of crushed ice debris. Simultaneous ice crushing failure is probable when the ice velocity is low, which makes the ice fail in the ductile mode with large compressive deformation and the vertical structure is narrow and compliant, which makes the extrusion or clearance of the crushed ice debris likely.
