| 摘 要： | 对十天高速公路软岩填料进行剪切强度试验,结果表明：软岩填料的强度特性是由细料、粗料特性以及粗细料比例所决定;强度参数随粗料含量以及干密度变化。可以通过合理配料等方法来确保软岩填料满足工程要求。研究结果可为软岩填料的工程应用提供参数。

| Abstract: | Shear strength tests of soft rock filling in Shiyan-Tianshui Expressway are carried out.The result shows: the strength characteristics of soft rock filling are determined by the characteristics of fine particles,coarse particles and its ratio;strength parameters varied with the coarse material content and dry density.It can ensure the engineering requirements by reasonable mix proportion.The study results can provide parameters for the application of soft rock filling in practice. |
