In recent decades due to the development and diversification of construction technologies, soil improvement procedures became a competitive and cost-effective alternative to increase the load-bearing capacity of the subsoil, while reducing deformations of the structure. Attributed to urbanization, lands with insufficient soil bearing capacity are becoming construction sites, for which it is essential to influence or increase the bearing capacity of the subsoil for the safety and compatibility of structures. Soil reinforcement with concrete elements is used in more and more construction project in Hungary. The structural behavior of traditional pile foundation is well known, and adequate standards are available during the planning process. On the other hand, soil improvement procedures, in our case for the design of rigid inclusion foundation no standards are available only guidelines and recommendations.Because of that in almost all cases, the design phase includes numerical modelling, which is used to prove the efficiency of the system and receive a more accurate picture of the real structural behavior.
In the forthcoming years intensive renovation and reconstruction works can be expected on the banks’ freshwaters of Hungary. For the rehabilitation of the shores of Lake Velence works are starting in 2020. To support these investments there has been a demand for prefabricated reinforced concrete sheet pile walls. Realizing the opportunity, a major player in the market of pre-fabricated reinforced concrete elements for water way construction, CSOMIÉP Ltd. decided to develop a reinforced concrete sheet pile wall. In this study the development and complex structural and geotechnical design concept are shown through the major structural behaviors and useable geometries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
