摘　　要：双线船闸闸首错位布置是一种新型的闸首结构型式。为了揭示错位布置闸首的受力与变形机理和进一步完善这种新型船闸结构的设计理论,针对实际工程,采用黏弹性边界和动力接触模型,研究了地震作用下错位布置闸首接触非线性对闸首结构应力及变形的影响,分析了设计地震作用下结构缝的张开情况及其对止水、中墩应力及变形影响。研究成果不仅为本工程的安全运行提供依据,也为这种新型结构的推广应用提供了科学依据。The lock heads with dislocation layout of the double lock is a new structural style.In order to reveal the mechanical and deformation of lock heads with dislocation in the double locks and to promote the design theory of this new lock structure,using the viscoelastic boundary and the dynamic contact model,the influence of contact nonlinearity on the structural stress and deformation under the action of earthquake is studied,the opening width of structural joints under the design earthquake and its influence on water seal,the stress and deformation of middle pier are analyzed on a practical engineering.The research results not only provide a basis for the safe operation of the project,but also provide a scientific basis for the promotion and application of this new structure.
