摘要：
Dissolution of gas and salts leads to the variation of groundwater property in geotechnical medium. By thermodynamic calculation the effect of the pH value of groundwater on chemical grouting is discussed. The effect is shown mainly in two aspects: one is gelling time of chemical grout, the other is the durability of products. At the same time some ionic species in groundwater may react with grout to precipitate, which affects chemical grouting.
