PS Infiltration Test of Earthern Architectural Sites for Different Moisture Content

摘要

In terms of consolidant protection of earthern architectural sites in humid environment,it is still at the stage of exploration in our country.Combaining with characteristics of consolidant project of earthern sites,this paper on the basis of consolidant techniques from JiaoHe Ancient City campaign makes an ascertainment to PS permeability property and consolidant effects at different moisture content by means of testing infiltration of the soil of JiaoHe Ancient City site for different moisture content.Prior to prepare remoulding samples of 1.40 to 1.45 g/cm3 for density,19%,17%,15%,13%,11%,9%,7%,5%,3%,1% for moisture content with site soil,then utilize PS solution at the modulus of 3.85 and the concentration of 5% to infiltrate into each sample respectively,and meanwhile test infiltration deformation,infiltration capacity and infiltration speed,then test resilience wave and unconfined pressive strength until samples to be completely dry in the air and analysis permeability property and consolidant effect of PS solution to site soil at different moisture content.The results of test manifest that it differs a lot for infiltration deformation,infiltration capacity,infiltration speed and intensity heightening of PS solution aider infiltration at different moisture content and illustrates certain regularities.The initial conclusion is that PS can adapt to consolidate architectural sites at the moisture contenof 3%～9%.
