Abstract

The paper presents the design and construction of an elliptical excavation for Porto Light Metro. Due to its original shape the solution took full advantage of the arch effect in the ground, adapting the Sequential Excavation Method to the vertical direction and achieving a novel, light and economic solution. In a first phase, the paper describes the construction method, referring also to economic and planning aspects of the excavation performed. The design is presented and discussed, including the presentation of the geotechnical tests performed and a brief analysis on the parameters assumed. The final part of the paper analyses monitoring results, focusing on the most surprising aspects of the behavior and on the main differences to the numerical calculations.
