濱海地區(qū)吹填海砂路用性能及其應(yīng)用研究
[Abstract]:Coastal areas rely on their natural geographical resources, fisheries, tourism has been rapid development, but highway construction problems are increasingly apparent: inadequate supply of soil, soil-derived poor quality. Based on the idea of turning waste into treasure, this paper puts forward a scheme of highway construction by using special sea sand in coastal area as roadbed filler.
In view of the above requirements, this paper mainly studies the applicability and application of dredged reclamation sand subgrade filling, and directs the construction relying on the project.
(1) The physical and mechanical properties of dredged reclamation sand in coastal area, such as particle size distribution, liquid-plastic limit index and salt content, were studied by laboratory tests.
(2) evaluate the road performance of the reclamation area by means of compaction test and CBR test.
(3) The solidification behavior of dredged reclamation sand in coastal area was studied by indoor unconsolidated undrained triaxial test.
(4) The pavement performance, salinization degree, rolling scheme and compacting performance of dredged reclamation sand in coastal area are studied by field test.
(5) The slope stability of dredged reclamation sand subgrade in coastal area is studied by theoretical calculation and field test respectively.
