摘要
Modulated potassium silicate solution (PS) has been applied widely for the protection of heritage soil in the arid area of northwestern China and obviously succeeded. However, protection of such site soil in the moist area is remained as one of research subjects. Based on the data of laboratory tests, the strengthening effect of PS for soil with relative higher water content is presented in this paper. The test data show,that the PS strengthening may result in the stabilization of soil structure framework and secondary support to the pores. This work should give a support to the further application of PS strengthening technology for heritage site soil.
