Parametrization design method for round double-wall steel cofferdam

Abstract

The invention relates to a parametrization design method for a round double-wall steel cofferdam. An existing design method is an empirical method, similar schemes of other projects are referred to in the protocolling process of related construction sizes, finite element trial is adopted, then, the related sizes are corrected, the main point of double-wall steel cofferdam design cannot be grasped integrally, and consequently the calculation process is complex, material waste is large, part of cofferdam structure stress is rather large, and the structural safety is low. It is necessary to tease the calculation process of the double-wall steel cofferdam design under the situation of considering the integrity, by means of a parametrization calculation manner, the reasonable structure of the cofferdam is considered in a unification manner, a reasonable structure and a related calculation formula for the round double-wall steel cofferdam design are given, and a cofferdam design person can primarily protocol the cofferdam structure sizes conveniently. Compared with double-wall steel cofferdams designed through the empirical methods of the other project, the round double-wall steel cofferdam designed in a parametrization manner has the beneficial effects that 20%-35% of material utilization amount is reduced, and great popularization significance is achieved.

Description

technical field [0001] The invention relates to the structural design of a double-wall steel cofferdam. Background technique [0002] Double-wall steel cofferdam is a common structure for deep-water foundation construction. Generally speaking, double-wall steel cofferdam has a large volume and high safety risk. It is necessary for cofferdam designers to consider structural optimization while ensuring the safety of double-wall steel cofferdam structure. The problem. The basic force condition of the double-wall steel cofferdam is mainly to resist the hydrostatic pressure. The influence of the hydrodynamic pressure and wave force on the overall structure of the cofferdam is relatively small. The loads of various cofferdam structures are simple and clear, and have unity. On the basis of summarizing other previous projects, this application proposes the idea of ​​parametric design, and constructs an evaluation function to optimize the cofferdam structure.
