摘要
为了研究泥质粉砂岩的崩解特性,本文采用将中风化程度的泥质粉砂岩置于充满不同PH溶液的耐崩解性试验仪中进行外动力作用下的崩解试验,对比并分析不同PH溶液对泥质粉砂岩崩解特性的影响,以及泥质粉砂岩在崩解试验过程中颗粒级配变化情况。试验结果表明:酸性环境对泥质粉砂岩的崩解性影响较碱性环境大;泥质粉砂岩的崩解性随着酸性的增强而逐渐增强,随着碱性的增强而逐渐减弱。
abstract ： In order to study the collapse of the argillaceous siltstone features, This paper puts the weathering degree of argillaceous siltstone with differ ent PH in the solution of collapse resistance tester disintegrating under outside force experiment was carried out, Contrast and analyze the different PH solution of argillaceous sihstone disintegration characteristics, and Pelitic siltstone in the process of the disintegration test, the change of the grain size distribution. The experimental results showed that Acidic environment on the influence on the collapse of the argillaceous siltstone is alkaline environment, Disintegration of argil laceous sihstone with the increase of acid increased, with the enhancement of alkaline weakened gradually.
