INTRODUCTION
My goal is to talk about artificial engineering structures in transport.
Tasks:
1)Define artificial structures;
2)Describe what is related to artificial structures;
3)Tell us more about bridges, overpasses, overpasses.
DEFINITION
Artificial structures are the collective name for structures erected at the intersection of rivers, streams, streams of rain and melt water, other railway lines, tramways and highways, mountain ranges, deep gorges and urban areas.
Artificial engineering structures provide:
1)safe passage of people over or under railway tracks;
2)stability of steep and deforming slopes;
3)regulation of water flows in order to protect railways from waterlogging and erosion.
