湿化崩解是膨胀岩的一个重要特性,崩解性是由其膨胀性等级、含水率、结构特征以及矿物成分等决定的。为了解南水北调中线工程南阳地区膨胀岩湿化崩解特性,进行了现场取样和室内试验。介绍了膨胀岩湿化崩解特性的试验方法和试验过程,重点研究了膨胀性等级和含水率对膨胀岩湿化崩解特性的影响,讨论了不同膨胀性等级的膨胀岩湿化崩解特征。在大量试验分析、研究的基础上,提出了以湿化崩解特征作为初判指标,实现了对南阳地区膨胀岩膨胀性等级的快速鉴别。
濕化崩解是膨脹巖的一箇重要特性,崩解性是由其膨脹性等級、含水率、結構特徵以及礦物成分等決定的。為瞭解南水北調中線工程南暘地區膨脹巖濕化崩解特性,進行瞭現場取樣和室內試驗。介紹瞭膨脹巖濕化崩解特性的試驗方法和試驗過程,重點研究瞭膨脹性等級和含水率對膨脹巖濕化崩解特性的影響,討論瞭不同膨脹性等級的膨脹巖濕化崩解特徵。在大量試驗分析、研究的基礎上,提齣瞭以濕化崩解特徵作為初判指標,實現瞭對南暘地區膨脹巖膨脹性等級的快速鑒彆。

The wetting-induced disintegration is a main feature of the expansive rock, and the disintegration is determined by the characteristics such as the expansive degree, water content, structural feature as well as the mineral composition. An in-situ sampling and indoor experiment was carried out in Nanyang area of Henan Province, the MRP of South-to-North Water Diver-sion, so as to study the wetting and disintegration characteristics of expansive rock. The experimental method and process are presented, especially the influence of expansive degree and water content on wetting and disintegration is researched. Based on a large quantity of experiments and studies, a quick identification method for the expansive degree of expansive rock in Nanyang ar-ea is put forward, in which the wetting and disintegration characteristics are adopted as the initial index.
