Bubbled Roller Compacted Concrete Dam: an idea of a hollow dam

Roller compacted concrete is widely known for its relatively low cost and short construction time. RCC gravity dams require high foundation (rock) bearing capacity. Research has been carried out which proposes to rationalise the amount of material in the dam by creating inner voids, in the shape of bubbles. As a key requirement, the introduced bubbles should not affect the dam stability and safety. The bubbles will reduce the self-weight of the dam and minimise the required rock bearing capacity. A system of pipes connecting the bubbles ensures drainage of the bubbles. The proposed dam would save about 12% of the required concrete volume. Different construction methods were studied and the best alternative is the use of precast hollow boxes. This decreases RCC placement in the dam by 32.5%. The objective is to speed the construction process and minimise the risk of the heat of hydration.

Topological optimisation technology of gravity dam section structure based on ANSYS partial differential equation operation

This paper uses the finite element method to explain the specific nature of numerical instability such as network dependence in the topology optimisation of engineering structures from the perspective of partial differential equations. Gaussian function filtering method reduces the global impact of local extremum on topology optimisation. Finally, the method is introduced into the topology optimisation of concrete gravity dams in hydraulic engineering, and the topology optimisation program is developed in conjunction with ANSYS software language to achieve the topology optimisation of building structures in hydraulic engineering from a technical perspective.

Build The Future - Gravity Dams: A Primeira Versão de um Aplicativo Mobile para Ensino de Estabilidade de Barragens à Gravidade

O desempenho pouco satisfatório dos cursos de Engenharia Civil nos exames de avaliação nacionais abre espaço para discussão sobre formas de facilitar a assimilação do conteúdo por parte dos alunos e alunas. O uso de novas tecnologias no ensino auxilia no atendimento a esta demanda. Neste sentido, o presente trabalho apresenta um software educativo para dispositivos móveis a ser utilizado pelos docentes no ensino do conteúdo sobre barragens à gravidade. Foi implementada uma estrutura de módulos para aprendizado, contendo capítulos conceituais e de simulação. A avaliação deste software obteve bons resultados tanto na visão de um professor especialista na área quanto na visão de um analista de tecnologia da informação.
