摘要： 路線設(shè)計是公

鋼塑土工格柵以高強鋼絲（或其他纖維），經(jīng)特殊處理，與聚乙烯（PE）或聚丙烯（PP），并添加其他助劑，通過擠出使之成為復合型高強抗拉條帶，且表面有粗糙壓紋，則為高強加筋土工帶。由此單帶，經(jīng)縱、橫按一定間距編制或夾合排列，采用特殊強化粘接的熔焊技術(shù)（超聲波焊接技術(shù)）焊接其交接點而成型。應(yīng)用領(lǐng)域： 公路、鐵路、橋臺、引道、碼頭、水壩、渣場等的軟土地基加固、擋墻和路面抗裂工程等領(lǐng)域。

路設(shè)計的核心，合理的路線方案是公路建設(shè)可持續(xù)發(fā)展的保障。文章通過對龍瑞高速公路路線設(shè)計的介紹表明，準確地把握山區(qū)高速公路的特點，制定項目的路線設(shè)計原則并靈活運用，能得到“安全、環(huán)保、舒適、和諧”的路線方案。

abstract: the route design is the core of the highway design, and reasonable route program is a guarantee of sustainable development of highway construction. through the introduction of longling-ruili highway route design, this paper accurately grasps the characteristics of mountain highway, establishes route design principles of the project and conducts application flexibly, which can get “safe, environmentally friendly, comfortable, harmonious” route program.
