阐述了土工合成材料在加筋路堤、加筋路面、边坡防护中的应用机理,研究了相应的选材原则。在宁夏黄土地区的道路工程中用土工合成材料处治黄土路堤沉陷、半刚性基层沥青混凝土路面的反射裂缝、道路边坡破坏等,工程实例证明土工合成材料能有效防治宁夏黄土地区的道路病害。
The application mechanism of geosynthetics in reinforced embankment, reinforced pavement and slope protection is expounded, and the corresponding selection principle is studied. In the road engineering of loess area in Ningxia, geocomposite material is used to treat loess embankment subsidence, reflection cracks of semi-rigid base asphalt concrete pavement and road slope failure. The engineering example proves that geosynthetics can effectively prevent and cure the road diseases in loess area of Ningxia.
