The Rion-Antirion bridge—when a dream becomes reality

Jacques COMBAULT

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 4,   Pages 415-426 doi: 10.1007/s11709-011-0130-x

Abstract: Opened to traffic in August 2004, the Rion-Antirion Bridge crosses the Gulf of Corinth near Patras in western Greece. It consists of an impressive multi cable-stayed span bridge connected to the land by two approaches. An exceptional combination of physical conditions made this project quite unusual: high water depth, deep strata of weak soil, strong seismic activity and fault displacements. In addition a risk of heavy ship collision had to be taken into account. The structure has been designed in view of challenging severe earthquakes and ensuring the everyday serviceability of the link as well. To make the bridge feasible, innovative techniques had to be developed: The strength of the in situ soil has been improved by means of inclusions; the bridge deck has been suspended on its full length, and therefore isolated as much as it can be.

Polypropylene microplastics alter the cadmium adsorption capacity on different soil solid fractions

Frontiers of Environmental Science & Engineering 2022, Volume 16, Issue 1,   Pages 3-3 doi: 10.1007/s11783-021-1437-z

Abstract:

Microplastics (MPs) are widely present in a variety of environmental media and have attracted more and more attention worldwide. However, the effect of MPs on the interaction between heavy metals and soil, especially in soil solid fraction level, is not well understood. In this study, batch experiments were performed to investigate the adsorption characteristics of Cd in bulk soil and three soil solid fractions (i.e. particulate organo matter (POM), organic-mineral compounds (OMC), and mineral) with or without polypropylene (PP) MPs.

Abstract:

Working capacity refers to the velocity output and force output of a manipulator.It is usually be represented by output capacity space.The results show that the effect of the gravity is a translation of the capacity space.This paper gives a method for the output capacity express especially for heavy duty manipulators.The output capacity space can be helpful to the driving parameters selection.
