In order to analyze the influence law of cement content and seawater corrosion on mechanical properties of cement-reinforced silty soil,samples of cement-reinforced silty soil with cement content 4%,8%,12%,16%and 20%soil were prepared.After 0,2,5,8,12 and 18 times of seawater corrosion dry-wet cycles,respectively,the uniaxial compressive strength,cohesion and internal friction angle of the specimens were tested.The effects of cement content and seawater corrosion on the mechanical properties of cement-reinforced silty soil were analyzed.The results show that:(1)With the increase of cement content,the uniaxial compressive strength and cohesion of cement-reinforced silty soil increase linearly,while the angle of internal friction decreases exponentially;(2)The compressive strength,cohesion and internal friction angle of cement-reinforced silty soil show a decreasing trend with the increase of the number of dry-wet cycles of seawater;(3)The increase of cement content can effectively improve the seawater corrosion resistance of the coment-reinforced silty soil.
