Two discussions of a paper with the aforementioned title by Houston, Mahmoud, and Houston, published in this journal (Volume 121, Number 4, April 1995), are presented. Discusser Day focuses on the small-diameter boring in the authors' in-situ collapse test. He states that the presence of loose debris or a disturbed zone at the bottom of the small-diameter boring would result in a greater collapse than as measured on undisturbed block samples. Discussers Ferreira, Lacerda, and Lopes report that they have developed a similar aparatus for testing collapsible soils. They discuss the methods employed with both apparatus and present data on Brazilian soils, with emphasis on a flooding technique used and the comparison between in-situ collapse under a plate inside an auger boring and laboratory collapse measured in an oedometer test. Discussions are followed by closure from the authors.
