Recorre-se a casos de obra para ilustrar os factores empíricos que influenciam a escolha do coeficiente de segurança de projecto, no contexto dos métodos de análise de estabilidade por equilíbrio limite. Os casos de obra referem-se a: 1) comportamento de um aterro de argila plástica colocada com teor de humidade superior ao óptimo, 2) comportamento de uma argila aluvionar estruturada e contráctil submetida ao carregamento de um aterro, 3) rotura progressiva ao longo de uma camada branda de bentonite, durante uma escavação, 4) rotura progressiva ao longo de uma camada de argila frágil de alta plasticidade, debaixo de uma barragem, 5) deformações cumulativas numa fundação branda de barragem, em resultado do carregamento cíclico devido à albufeira.
