| 摘 要： | 分别针对纯砂地基、水平加筋地基和新型三维立体加筋(简称横-竖加筋)地基进行了多组模型试验。主要研究了单层横-竖加筋深度和横-竖加筋层数对地基的影响,并通过与水平加筋地基的比较,结合横-竖地基砂土滑移面的形状,初步分析了横-竖加筋地基的加固机制。试验结果表明,同等试验条件下,横-竖筋的加筋效果较水平筋的好,对于单层横-竖加筋地基,加筋效果随加筋深度的增加而减弱,加筋深度超过一定范围后,加筋对地基受力性能的改善不明显。对于多层横-竖加筋地基,随加筋层数的增加,承载力增加,沉降减小。

| Abstract: | According to model tests of pure sand foundation,horizontal reinforcement foundation and horizontal-vertical(H-V) reinforcements foundation,the influences of single layer H-V reinforced depth and number of H-V reinforced layers on foundations are studied.Through comparing the horizontal reinforcement foundations and combining the sliding surface of H-V reinforced soil,the reinforcement mechanism is analyzed.The test results show that the reinforced effect of H-V reinforcements is better than that of horizon... |
