【摘要】 为了进一步探明灰土地基鼓胀的原因及其发生机理,对场地内采取的素土和灰土土样进行检测、分析,在灰土中发现了膨胀能力极强的钙矾石和碳硫硅钙石。论文对钙矾石和碳硫硅钙石的生成过程和生成条件作了进一步探究,揭示了钙矾石和碳硫硅钙石生成的化学反应过程及诱发化学反应的条件,并对钙矾石和碳硫硅钙石引起灰土地基鼓胀病害的抑制措施进行了初步尝试。更多还原

【Abstract】 In order to further clarify the cause and mechanism of lime-soil foundation swelling,the plain soil and lime soil samples taken in the site are tested and analyzed,ettringite and thaumasite with strong expansibility were found in lime soil. In this paper,the formation process and conditions of ettringite and thaumasite were further explored,the chemical reaction process of ettringite and carbosulfite and the conditions inducing the chemical reaction were revealed,and the preliminary attempt was made to inhibition measures the swelling of lime soil foundation caused by ettringite and thaumasite.更多还原
