%X To investigate the effect of nano-MgO on cement-treated seashore soil, mechanical test and microscopic test were conducted on nano-MgO modified cement-treated seashore soil (NmCS). The mechanical performances of NmCS samples with varied cement content and nano-MgO content were examined via indoor direct shear test. Furthermore, the micro-structural characteristics and mechanism were studied by using SEM technology. Test result unveiled that: (1) there exists an optimum content of nano-MgO for NmCS. Specifically in the test of the present research, the optimum content of nano-MgO is 10‰. (2) Cement-treated seashore soil in the absence of nano-MgO is dominated by loose-structure and small particles; while NmCS with 10‰ nano-MgO is the most compact, reflected as in the improvement of mechanical strength.
