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 horizontal reinforcement at the same experiment condition; the bearing capacity decreases with the increase of the single layer H-V reinforced depth; effect of reinforcement on foundation bearing capacity is not obvious when the reinforced depth exceeding a certain range. For multilayer H-V reinforced foundation

bearing capacity increases and settlement decreases with the increase of number of reinforced layers.
