摘要
表面加固是防止土遗址风化的一种重要手段.加固效果的系统评价是土遗址加固科学研究的关键环节之一,关系到土遗址能否耐久保存.从土遗址加固前后的颜色变化、透气性、渗透速度和深度、力学强度、透水性、土壤孔隙度及孔隙率、重量变化、pH变化以及耐老化性等方面对土遗址的防风化加固效果评价指标进行了综述,以期为土遗址保护工作者更好地选择保护材料提供理论依据.
Surface strengthening is one of the most important methods of soil sites anti-weathering.The system evaluation of reinforcement effects is the scientific research key of soil sites reinforcement,which is related to the durability of soil sites.It summarized the reinfoecement effect evaluation indexes of soil sites anti-weathering including color changed,air permeability,penetration speed and depth,mechanical intensity,water permeability,soil porosity and pore porosity,the changes of weight and pH value,aging resistance and so on,in order to providing theoretical basis for the soli sites conservation workers protectors to choose protection materials better in this paper.
