摘要
为了研究不同因素对土工格室加固层路基沉降的影响,主要从不同压实度、格室高度和焊距处理后的路基进行室内模型试验,结果表明:压实度越大,路基承载力越大;路基承载力随土工格室高度的增加而呈非线性增大,随格室焊距的增大而呈非线性减小。当格室高度为150 m,焊距为500 mm时,其处理软弱路基的"性价比"最高,达到了经济节约的效果。
In order to study the effect of different factors on the geocell reinforced layer of subgrade settlement,an indoor model test is carried out in the subgrade which is mainly treated with different degree of compaction,height and distance of welding.The results show that the greater the compactness,the greater the bearing capacity of the roadbed.T h e bearing capacity of the subgrade increases linearly with the increase of the height of the geotextile chamber,and decreases nonlinear with the increase of the welding distance.W h e n the height of the cell is 150 m and the welding distance is 5 0 0 m m’the“price to price”of soft subgrade in geotextile room is the highest,which has achieved the effect of economic saving.
