In this study, various kinds of deformation analysis of collapsible loess are needed. Ground settlement tester, GJY K0 tester produced by Suzhou Longstan Automation Factory and ADINA software are used. Experiments show that under the action of different filling heights, different isotropic stresses are applied to the foundation, and the hidden stresses of the loess are gradually decreasing. At the same time, the higher the height of the fill, the faster the decline of the underlying stress of the foundation loess; with the increase of time at the bottom of the cushion, the corresponding underlying stress at the midline decreases, while with the increase of the height of the fill, the corresponding underlying stress at the midline rises; the study of the underlying stress at the bottom of the pile is set up differently. Under certain time and position of the pile bottom, increasing the isotropic stress can increase the hidden stress at the corresponding pile bottom, and change the filling height at the pile bottom has little effect on the hidden stress at the pile bottom. Under the combined action of water content and isotropic stress, they are positively correlated with the change of lateral stress. With the increase of isotropic stress, the K0 coefficient rises as a whole. This study can provide a strong reference for the deformation characteristics of collapsible loess itself, and help construction workers to improve the safety of the project in the field of engineering construction.<\/jats:p>","DOI":"10.3233\/jcm-193957","type":"journal-article","created":{"date-parts":[[2019,11,5]],"date-time":"2019-11-05T10:54:14Z","timestamp":1572951254000},"page":"697-713","source":"Crossref","is-referenced-by-count":0,"title":["Experimental study on deformation characteristics of collapsible loess under isotropic stress"],"prefix":"10.66113","volume":"20","author":[{"given":"Yajun","family":"Jia","sequence":"first","affiliation":[{"name":"Civil Engineering and Architecture Institute, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi 710048, China"},{"name":"Gansu Forestry Technological College, Tianshui, Gansu 741020, China"}]},{"given":"Cunli","family":"Chen","sequence":"additional","affiliation":[{"name":"Civil Engineering and Architecture Institute, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi 710048, China"}]},{"given":"Dengfei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Civil Engineering and Architecture Institute, Xi\u2019an University of Technology, Xi\u2019an, Shaanxi 710048, China"}]}],"member":"55691","reference":[{"issue":"638-640","key":"10.3233\/JCM-193957_ref1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.4028\/www.scientific.net\/AMM.638-640.393","article-title":"Application of lime-soil compaction pile method for loess foundation treatment","author":"Huang","year":"2014","journal-title":"Applied Mechanics and Materials"},{"key":"10.3233\/JCM-193957_ref2","doi-asserted-by":"crossref","unstructured":"S.
