Abstract:

Strength and stability of reinforced soil depends on intercrossing and tensility of reinforced materials, and friction between reinforced material and soil. By means of SEM photos, it is observed that SH agent is infiltrated through the pore of wheat straw, and adhered to its surface. For studying its tensility, maximum tensile and elongation of wheat straw with one stem node and without stem node, is tested in the condition of original, soaked in sea water, marinated in SH agent, and soaked in sea water after marinating in SH agent. It has been certified that the maximum tensile and elongation of wheat straw without stem node is more than that of wheat straw with one stem node. Respectively comparison on the marinated in SH agent and original, and soaked in sea water after marinating in SH agent and soaked in sea water, the maximum tensile and elongation of wheat straw marinated in SH agent is more than that of original wheat straw. SH agent benefits to increase the tensility of wheat straw.

Key words: wheat straw, reinforced material, maximum tensile, maximum elongation, inshore saline soil
