description: Theme of the final qualification work: "Development of a project for the overhaul of the Admiralteysky bridge in Kolpino."
This work is devoted to the development of overhaul options for the Admiralteysky bridge in Kolpino, the search of the causes of defects in the bridge structure and the proposal of measures to prevent the buildup of deformations of the span.
Tasks solved during the study:
1. A full examination of the bridge structure and the preparation of a list of defects.
2. The study of the nature of creep of concrete, factors affecting the occurrence and resumption of the process.
3. Development of overhaul options and calculation of two groups of limit states for each of them.
4. Calculation of a statically indefinable arch with a non-linearly distributed load as part of the calculation of 1 overhaul option.
5. Drawing up a local estimate for the replacement of pavement.
6. Drawing up a technological map for the replacement of the barrier fence.
A significant part of the material was collected on the basis of SPb GBU "Mostotrest" during a summer internship. In particular, a full survey of the Admiralty Bridge of the city of Kolpino was performed.
In the course of the final qualification work, two options for the overhaul of the bridge structure were developed: alignment of the longitudinal profile with the help of a lightweight arch structure made of expanded clay concrete and external reinforcement with spreel ropes. As part of the development of the first option, a truncated PVP pipe was manually calculated under load from liquid expanded clay concrete - a statically indeterminate arch with a non-linear load distribution. As a result, plots of internal forces were obtained: bending moment, longitudinal and shear forces, and a strength test was performed according to the normative method.
The calculation of the second option was completely performed in the Midas.Civil 2019 software package, the maximum values of internal efforts were compared with the limit values from the regulatory literature.
Based on the analysis of technical and economic indicators, preference was given to the first option.
Also, as part of this final qualifying work, a local estimate was made for the replacement of pavement and a technological map for the replacement of the barrier fence.
