土工格栅、格室加筋砂垫层 大模型试验及抗变形能力分析
Geogrid-and Geocell-Reinforced Sand Blanket: Model Test and the Ability to Reduce Deformation
-
摘要: 对土工格栅及土工格室加筋砂垫层处理松软地基进行了室内大模型试验,对其抗变形能力进行了较为 详尽的试验及理论分析。试验结果表明,加筋垫层能够有效分散荷载,显著提高地基K30值,使地基下沉减少 40%左右。Abstract: In this paper, amodel teston soft subsoil confinedwith sand blankets reinforced bygeogrids and geocells is presented. The ability to resist deformation of the subsoil is discussed in detail. The sand blankets distribute the load effectively, so that the value ofK30is remarkably increased by over 57% and the deformation of foundation is decreased by about 40%.
