Abstract:
This paper is reviewing and studying the physical properties of the expanded polystyrene plastics lightweight materials and its application scope. Relying on the high embankment culverts projects of Lanzhou to Haishiwan expressway, throughout the laboratory compression and creeping tests, the stress-strain and creep behaviors of EPS with different density under confined or unconfined conditions are analyzed on the bases of compression test and static triaxial test. Besides, the reducing-load character of EPS plate with different thickness in engineering applications is studied for the entities projects. The results showed that: the density of smaller EPS material is not suitable for projects such as the optimization of embankment fill a substitute; also, under the confined effects condition, the stress value when the EPS materials reach the yield stage is high than that under the condition of unconfined effects; the density moderate has a certain thickness of the EPS material in industrial engineering applications since played the role of a good reducing-load. 10 figs, 10 refs.
