The safety culvert composed of hollow high-performance concrete blocks is designed to reduce the risk injury in event a collision. This work presents new design with an opening for water flow, tests it, identifies its weaknesses, and discusses possible improvements. numerical model constructed, validated by experiment, used study effect parameters on load capacity, compression behaviour, failur...

Abstract—Expanded polystyrene (EPS) geofoam is often used in below ground applications in geotechnical engineering. A most recent configuration system implemented in roadways to protect lifelines such as buried pipes, electrical cables and culvert systems could be consisted of two EPS geofoam blocks, “posts” placed on each side of the structure, an EPS block capping, “beam” put atop two posts, ...

In many large ecosystems, conservation projects are selected by a diverse set of actors operating independently at spatial scales ranging from local to international. Although small-scale decision making can leverage local expert knowledge, it also may be an inefficient means of achieving large-scale objectives if piecemeal efforts are poorly coordinated. Here, we assess the value of coordinati...

To study the adaptation of current automobile design load highway bridges in China case separation passenger cars and trucks, a statistical method is proposed this paper to data special lanes for trucks. Four typical truck-based were selected as object, from which information continuous truck fleet was truck-specific lane flow samples, technical parameters vehicles determined. Finally, introduc...
