| 摘 要： | 特定模数硅酸钾溶液(PS)已广泛的用于我国西北干旱地区土遗址加固保护工程中,并且取得了显著的效果.但是PS对潮湿地区遗址土加固效果,目前尚缺乏成熟的理论和实验验证.本文从室内试验的资料出发,研究PS对潮湿地区土遗址非饱和土的增强效应.本次研究土样取自位于潮湿环境中的浙江杭州良渚土遗址(3000 B C.),在实验室内对...

| Abstract: | 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 soil samples taken from Liangzhu civilization site(3000 B.C.)were modulated to obtain higher water content up... |
