%X As a material of  light weight and high strength, foam concrete is usually used in road engineering at coastal region  subjected to  different static and dynamic actions such as deadweight, wave force, and transportation loading. Static and dynamic triaxial tests were conducted to investigate  the deformation and strength of foam concrete, and the influence of dynamic loading history on material strength was also discussed. Results indicate that  under static loading, the deformation of foam concrete showed  elastic tendency followed by plastic tendency subsequently, with the static compressive strength  about 1 040 kPa; under small  dynamic loading, deformation of foam concrete gradually became stable and dynamic elastic modulus changed slightly  with the increase of strain; dynamic failure of foam concrete would  be triggered if the dynamic loading amplitude was  large. In addition, static compressive strength increased first and then decreased with the increasing amplitude of advanced dynamic loading. The results revealed the  mechanical mechanism of foam concrete under static and dynamic loadings, which can be taken as reference for similar projects.
