土工格室是一種新型的土工合成材料，它工程性能優(yōu)越，幾年來被廣泛用于
現(xiàn)代土木工程領(lǐng)域，并取得了良好的加固效果。本文通過理論分析、公式推導(dǎo)、
數(shù)值計算等手段，主要進行了以下幾方面的工作:
1、分析了土工格室的加筋機理，結(jié)合相關(guān)工程實例將立體加筋與平面加筋
相比較，并分析了產(chǎn)生這兩種加筋效果差異的原因。
2、利用變分原理，推導(dǎo)出文克爾地基上加筋墊層的撓度計算公式，總結(jié)了
公式中各參數(shù)的確定方法，并驗證了該公式的合理性。
3、采用Plxais有限元軟件將三種形式的路堤進行數(shù)值分析，分析了軟土層
厚度、格室墊層模量、格室鋪設(shè)寬度、堤底寬度、墊層厚度等影響加筋效果的幾
個因素，所得的結(jié)論對工程實踐具有一定的參考價值。
