Abstract: Solidified saline soil in inshore with polymer-SH agent and lime has a very high compression strength, tensile strength and stability in nature and after soaking in comparison with solidified soil only by lime because soil particles were enveloped by SH agent and formed web structure between particles and in voids. Compression strength of solidified soil decreased after applying sinusoidal load, and has some attenuation with the growth of fatigue times under a preload value and constant amplitude of load. Value 30×103 times is a special starting point from which strength falls. It has been certified that SH agent has made the stable web structure in soils when two weeks and it is better when four weeks with the help of observation of SEM’ pictures. This web structure remain stable after soaking, it is obvious that SH agent’s solidifying reaction is no reversibility in soils.

Key words: solidified saline soil in inshore, polymer, SH agent, compression strength, fatigue test, microstructure
