土工格室和土工网加固基床效果静态模型试验

摘要: 分析了土工格室和土工网加固路基基床的主要机理,介绍了5组不同基床结构的静态原型尺寸模型试验,通过基床结构刚度K30值、应力和变形的测试,验证了土工格室和砂构成的基床垫层在改善基床应力分布、提高基床刚度、减少基床变形等方面的作用,并分析了其随有关因素变化的相关规律,而土工网和砂构成的基床垫层只能十分有限地改善基床的性能。两种材料的试验结果对比表明,与土工网垫层相比,土工格室垫层能够更有效地提高基床以及整个线路结构的刚度和强度。

Abstract: The mechanismof subgrade strengtheningwith geocells and geonets is discussed. To compare the effects of geocells and geonets on subgrade strengthening under static loads, full scale model tests were conducted for different subgrade structures. It is shown that geocells are better than geonets, although both can improve the performances of subgrades.
