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K3 0 值 ,使地基下沉减少40 %左右。
In this paper, a model test on soft subsoil confined with sand blankets reinforced by geogrids 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 of K 30 is remarkably increased by over 57% and the deformation of foundation is decreased by about 40%.
