| Abstract [eng] |
In this work it is discussed the main types of gravity quay structures. The selected model quays elected the most appropriate model of the Šventoji port reconstruction. Šventoji port location chosen in order to be able to use real calculation of loads (characteristic of the area) and the depth of the port, because at this time (2015-2016) it is created different port reconstruction vision. The theoretical part is performed a literature review of five major gravitational quay structures (block, monolithic array, abutment, caisson and angular type quays). Here is a discussion of the main quay of these design principles, and operating load. The exploratory part is selected the five most commonly used in the construction quay and ten main criteria. These indicators have been submitted for evaluation by T. Saaty pairwise comparison scale to expert group. The data are used for calculations. Preferred gravitational quay construction type selection using Fuzzy Moora method. Using this method is selected block quay construction type. For optimal results, this type is more detailed and concluded five quay alternatives. For each alternative that is checked it is a required track thickness of the rock fills, the possible maximum block height required for the concrete surface preparation (coefficient of friction), and calculated the preliminary price. Using these and additional data is made the objective function with appropriate limitations and found the optimal gravitational quay option. |
