本文从寒冷地区高等级公路边坡防护存在的问题分析入手,引入新材料即土工合成材料制品:土工三维网、土工格室,根据边坡加固原理,充分利用其自身工程特点,进行野外实际工程对比试验,得出了初步试验结论。文中介绍了不同防护措施的设计施工要点及工程造价对比。本文介绍的内容为交通部“九五”攻关课题“季冻区高等级公路边坡防护实用技术的研究”中的一部分。
This article starts with the analysis of the problems existing in slope protection of high-grade highways in the cold area. The new materials, ie, geosynthetics products: geosynthetics, geocell, are introduced. According to the principle of slope reinforcement, the project makes full use of its own engineering features, Contrast test, reached the preliminary test conclusion. The paper introduces the design and construction of different protective measures and construction cost comparison. This article describes the contents of the Ministry of Communications “95 ” research topic “section of the research on practical technology of slope protection of high-grade highway in seasonal frost ”.
