Interaction Research Between Prestressed Ship Locks Structure And Foundation On The Elastic Foundation

Interaction question between shiplock structure and the foundation soil is a quite complex question.Previous research for ordinary ship lock structure was mostly from the elastic foundation beam, but research for prestressed ship lock structure were rare.For better research distortion as well as stress characteristic of prestressed ship lock baseplate,in this paper,ship lock baseplate is prestressed in the double-parameter foundation model,and prestressed loads is converted into equivalent nodal loads by constructing a cubic spline interpolation function,so prestressed ship lock baseplate can be calculated with the same method of calculating the general elastic foundation beam.In this paper,the influence of the two parameters k and Gp and prestress layout to prestressed ship lock baseplat calculation results is also analyzed. Matlab software is used to program the procedures to solve the problem.The procedures are strong applicable to rapidly calculate settlement, the foundation forces and the internal forces of the shiplock baseplate.Finally,the method is applied in the engineering example,YingShang prestressed shiplock, and the calculation results are compared with the finite element software ANSYS calculation results.The results of two calculations can be a good fit.The calculation results show that double parameters method can be very good calculation method calculating prestressed shiplock baseplate and can provide a good guideing significance for the prestressed foundation structure's scientific research, design and construction.Especially,it is very important for the further study of the prestressed shiplock's settlement,foundation forces,internal forces calculation.
