一种黄土脱敏加固新材料的试验研究

为了保护陕西延安地区的革命旧址，主要针对窑洞顶板渗水、窑面剥落、水土流失等病害问题，开展黄土脱敏新材料室内试验，研发适用于保护革命旧址的黄土加固新材料。通过对革命旧址的工程病害进行宏观调查，收集整理相关资料，选取典型案例进行详细调查，分析病害发育类型、发育特征、形成条件及成因机制；开展室内试验，分析黄土基本物理力学肚质，重点对黄土水敏性、渗透性和土水特征曲线关系进行研究；针对水土流失和坡面滑塌问题，对黄土固化前后的微观结构、渗透性进行对比分析。

Experimental Study on a New Material for Loess Desensitization

In order to protect the revolutionary site in the Yan''an area of Shaanxi Province, the main problems of the seepage of the roof of the cavern, the flaking of the kiln, soil erosion, etc., were to carry out indoor tests of desensitizing new materials for loess, and to develop new materials for loess reinforcement suitable for the protection of the revolutionary site. Through a macro survey of the engineering diseases of the revolutionary site, collect and collate relevant materials, select typical cases for detailed investigation, analyze the disease development type, development characteristics, formation conditions and genetic mechanism; carry out indoor experiments, analyze the basic physical mechanics of the loess, focus The relationship between water sensitivity, permeability and soil-water characteristic curve of loess was studied. The microstructure and permeability of loess before and after solidification were compared and analyzed for soil erosion and slope slippage.
