土工格室加筋路堤机理及沉降计算方法的研究（78页）.rar

（78页）摘要
土工格室是一种新型的土工合成材料，它工程性能优越，几年来被广泛用于
现代土木工程领域，并取得了良好的加固效果。本文通过理论分析、公式推导、
数值计算等手段，主要进行了以下几方面的工作:
1、分析了土工格室的加筋机理，结合相关工程实例将立体加筋与平面加筋
相比较，并分析了产生这两种加筋效果差异的原因。
2、利用变分原理，推导出文克尔地基上加筋垫层的挠度计算公式，总结了
公式中各参数的确定方法，并验证了该公式的合理性。
3、采用Plxais有限元软件将三种形式的路堤进行数值分析，分析了软土层
厚度、格室垫层模量、格室铺设宽度、堤底宽度、垫层厚度等影响加筋效果的几
个因素，所得的结论对工程实践具有一定的参考价值。
