Abstract in Portuguese
Este trabalho relata resultados de estudos sobre drenagem de camadas próximas à superfície que visam contribuir para aperfeiçoar o entendimento de comportamento da fase não saturada de solos, e disseminar o uso de elementos finitos para estudo de movimento de água em componentes que constituem a plataforma de vias. Descreveram-se e comentaram-se tópicos sobre as relações entre o formato de vias e a drenagem na estrutura de vias, processos para estimativas de vazões percoladas e infiltradas em solos por métodos simplificados, tópicos sobre a evolução do estudo de movimento de água e estimativa de medidas sobre propriedades de solos não saturados. Para estudo de caso se adotou a simulação com elementos de volume de sólido e método dos elementos finitos para com dados publicados sobre propriedades de solo arenoso ou argiloso obter dados para testes estatísticos que ressaltassem as diferenças entre as vazões estimadas com uso da condutividade hidráulica constante e de solo saturado, e a condutividade que incluísse o solo não saturado. Os dados usados foram obtidos por simulação, que estimou vazões percoladas e infiltradas, que foram submetidos a teste de hipóteses sobre diferenças de médias. O objetivo proposto foi atingido discutindo resultados de análise sobre a significância estatística de diferenças entre vazões percoladas.

Abstract in English
This work reports the conclusions of studies on draining water from surface layers of a way structure that aim to contribute to the knowledge on the behavior of non saturated ground, and to spread the use of the finite element technique for studies on the water movement inside components that constitute these platforms. It was discussed: an introduction on highways in Brazil, topics that had motivated the studies, methods and processes for treatment of the non saturated phase of the water movement. It was described and commented topics on the relations between the format of ways and the draining in their structure, processes to estimate the percolation and infiltration outflows using simplified methods, topics on the evolution of the study movement of water and estimating measures on non saturated ground properties. For case study it was adopted the simulation using elements of solid volume and the finite element technique obtained from bibliographical data on saturated and non saturated sand and clay properties, including the hydraulic conductivity. The tested data had been gotten by simulation, and had been submitted to the test of hypotheses on differences of percolated water volumes. The main objective was reached discussing statistical results on the significance of the differences among percolated volume of water.
