Abstract
The applicative research project Retaining Structure Optimisation considers optimisation of design and execution of reinforced concrete retaining structures in geotechnical practice. The project bases on simultaneous optimisation of retaining structures topology and prime costs considering ultimate and serviceability limit state conditions of linked with geomechanical interdependences fulfilling European standards. Attention is focused on optimisation of anchored and non-anchored pile walls, where limit states of bearing capacity will be proved by original interactional solutions and new cognitions acquired with bearing capacity researches of RC piles. Existing geomechanical solutions of embedded retaining structures bearing capacity in homogenous ground will be expanded and completed by solutions for heterogeneous ground and with solutions of anchored and embedded retaining structures that are mostly used in geotechnical practice. Flexural and shear bearing capacities of RC piles are indistinct (they limit project economy to a high degree) because of technology conditions that lead to essential too big and according to existing regulations also intolerable protecting coats of concrete. In proposed research projects will be proved the actual bearing capacities and criterions for determination of cracks in RC piles. This will enable more correct design of reliable and economical retaining structures. The structure system is presented with foundation ground, retaining structure and/or geotechnical anchors. In the optimization process will be considered all interactional conditions of activation of influence and resistance at ultimate and serviceability limit states, bearing capacity conditions of structural elements with appurtenant statical system and adequate technologies. The problem is formulated using mathematical programming method MINLP with objective function presented by project costs, which fulfill given safety and reliability conditions.
