| 摘 要： | 松散堆积体型斜坡在虎跳峡工程区河段两岸普遍发育,研究其剪切强度对于此类库岸斜坡的稳定性评价具有重要意义。作者设计了堆载式加荷直剪试验方法,并经野外大面积现场试验,获得了堆积体直剪时的剪应力-应变关系曲线,对堆积体的剪切强度性质进行了相应的理论分析,同时为工程区堆积体稳定性评价提供了可参考的c、φ值。

| Abstract: | There are large numbers of incompact-deposit bodies in Tiger-leaping Gorge area of Jingsha River. The shear strength properties of the deposit bodies are very important to the slope stability analysis. In this papor, pile-loading direct shear test was put forward and carried out in fields synchronously. Though the results we obtain the stress-strain relation curves of deposit bodies, at the same time, the shear strength parameters were attained too. |
