In this work ice-resistant stationary platform located on Rakushechnoe field is considered. The research set the following goals: 1. Determination of loads on construction from water flow, wind, ice and waves; 2. Stability testing of construction tilt and inplane shear: 3. Draw the diagram of footing floating stability; 4. Determination of static and dynamic heel and trim angles. During the work, the values of the loads from different directions were found. Maximum efforts, which were used in tilting and inplane shear testing, were determined. Also, the diagrams of stability during construction transportation and installation under loads of wind and water flow were found. As a result, stability tests were carried out, which were carried out with a margin. Also, floating stability tests were carried out on the basis of which it was found that the maximum theoretical tilt of the bigger pillar is 10,9° and the lesser pillar is 5,5°. |
