Abstract
The article presents the process of creating a computational model for the stability analysis of a harbour wharf’s embankment with regards to its failure. The described elements that were taken into account at the stage of data preparation are: historical analysis of the structure (structural calculations, and the calculations of the stability of the embankment), results of the author’s own soil and material tests (concrete, steel), environmental conditions (atmospheric and water), the possible load systems that acted on the facility, and also the results from the 3D model of the wharf’s structure. On this basis, five computational schemes were prepared for computer simulations of the stability of the embankment in a plain state of deformations. Various stages and conditions of its operation were taken into account. In conclusion, a possible course of the process of destruction of the structure of the harbour wharf, and the river embankment that cooperates with it, was proposed.
Highlights
The water system of the Odra river in Wroclaw mainly consists of: the current river bed, the old Odra river bed, and the city, flood and navigation channels (Fig. 1).The river quays are very diverse in terms of their geometrical and structural shape, which is related to their function
The following can be distinguished: canal quays in the form of unregulated river banks (Fig. 2), municipal recreational quays (Fig. 3), quays protected by stone
Where is the Rcx is the force acting on the sterns of the barges, which is reduced to the viscosity resistance [kgm/ s2], cF is the drag coefficient—1.0 (–), r is the water density—1000, u is the speed of the water current—1 (m/s), W is the wetted area of the hull (m2)
Summary
The water system of the Odra river in Wroclaw mainly consists of: the current river bed, the old Odra river bed, and the city, flood and navigation channels (Fig. 1). The conducted and described field and laboratory tests, as well as the historical analysis of the facility, formed the basis for building a computational model of the reinforced concrete structure of the wharf in order to simulate the process of its destruction. This was followed by the creation of numerical models of the behaviour of the embankment in order to determine possible variants of its loss of stability (Chapter 5)
