Design method for connection of maritime work module and pile

Abstract

The invention relates to the technical field of ocean engineering, especially to a design method for connection of a maritime work module and a pile. The method comprises the steps of: 1, arranging aboundary condition of a maritime work module as a hinge, and limiting linear displacement of the maritime work module in the X direction, the Y direction and the Z direction, wherein the number of point locations for limiting horizontal displacement of the maritime work module in the X direction and the Y direction is two; 2, designing the structure of the pile according to the support counterforce of the maritime work module; 3, completing an overall calculation report model combining the maritime work module and the pile according to the structure of the pile; 4, performing limiting design of the maritime work module and the pile hinge structure; and 5, checking the limiting design of the hinge structure of the maritime work module and the pile. In the connection design of the maritime work module and the pile, the construction efficiency is improved, the design input time is saved, the design process is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a design method for connecting a marine engineering module with a pile. Background technique [0002] In the connection between the offshore engineering module and the basic structure, rigid connection is currently the commonly used method. The principle is: after the offshore engineering module is inserted into the basic structure, the basic structure and the ring plate are welded in a circle by using the ring plate and the insertion tip , to achieve rigid connection; or to achieve rigid connection through grouting. [0003] refer to Figure 8 , is a structural schematic diagram of the rigid connection between the offshore engineering module and the basic structure in the prior art. [0004] In the existing technology, when the foundation structure and the ring plate are welded, it is necessary to use the overhead welding method at the welding place to make the offsh...

AI Technical Summary

Problems solved by technology

[0006] refer to Figure 9 , when the boundary condition of the offshore module is rigid connection, during the design process of the connection between the offshore module and the pile, there is a redistribution of the bending moment between the offshore module and the lower foundation structure, and the engineer must update it many times during the design process The model is used to ensure the accuracy of the design, which leads to a cumbersome design process and a long design time. In actual operation, in order to meet the requirements of the foundation design, the load factor of the offshore module is given large enough to ensure the support of the offshore module. The reaction force can cover all possible changes in the later stage of the design, resulting in a large structural size and increasing the cost of the overall design of the offshore platform
