土工格栅加筋垫层的设计和应用

Designation and Application of Georgrid Reinforcement

各种加筋材料与土的界面摩擦特性试验结果表明 :用经编土工格栅作为加筋材料的砂砾垫层 ,其加筋效果最好。在分析国内外加筋地基承载力计算方法的基础上 ,提出了加筋垫层的实用计算公式 ,并以泉州市朝天门城楼工程的土工格栅垫层地基为例进行计算 ,通过现场载荷试验加以检验。

The testing result of the interaction characteristics between different reinforced materials and soils indicates that the effect of the warp-knitting-geogrid-reinforced gravel cushion is the best.On the bases of analyzing different calculations of the bearing capacity of reinforced foundation,the article put forward a practical calculation formula.And took Quan Zhou City's ancient structure of city gate building(chaotianmen)for example to do the calculation.Then verified the result by the in-site loading tests.
