摘要
为研究宝顶山石窟区造象岩壁风化破坏及渗水危害的作用机理，选择不同类型风化产物进行定期采样监测。本文重点论述了外围岩石和造象岩壁风化产物的化学成分及矿物成分、风化产物可溶盐的化学特征及可溶盐类型，以及这些特征的多年变化规律，分析论证了可溶盐不同水化学成因类型的形成特征，为防风化防渗水危害治理措施提供可靠依据。
In order to understand the mechanism of damage of carved rockwall of Baodingshan Grotto by water seepage and weathering,regular sampling and survey are carried out for different types of weathering products selected.This paper deals with the chemical and mineralogical compositions of weathered products from surrounding rock and carved rockwall,chemical characteristics and types of soluble salts in weathering products,and perennial variation of these characteristics in many years.The characteristics of soluble salt formation due to different types of hydrochemical factors are analysed and discussedn, the results can used as a reliable base for protective measures against damage from weathereing and water seepage.
