| 摘 要： | 软弱夹层影响边坡稳定和爆破效果。特定软弱夹层的含水率和颗粒组成随着气候变化和时间推移会有所变化。通过对张坝沟石灰石矿山软弱夹层土样的室内模拟剪切试验,探讨泥质软弱夹层的内摩擦角与其颗粒组分和含水率之间的定量关系,建立了该软弱夹层的内摩擦角与其含水率和粗颗粒含量的相关方程。在此基础上进一步分析了不同粉砂粒含量的土在相同含水率时的摩擦角变化规律及其原因。

| 关 键 词： | 软弱夹层 含水率 摩擦角 模拟剪切试验 |

| Abstract: | Weak intercalation usually has a bad impact on the stability of rock slope, furthermore, some changes will happen to the granule composing and water ratio along with time passing and the climate changing, for special weak intercalation. A correlative equation of the friction angle, water ratio and the proportion of coarse granule was founded and the range of its application was indicated according to the laboratory simulation shear testing of Zhangbagou Limestone Mine' s weak intercalation. Moreover, the friction angle' s change rule and the reasons of different granules were analyzed and pointed out under the same water ratio. |
