盖孜河塔什米力克引水工程边坡稳定分析

Slope Stability Analysis of Tashilmicik Water Diversion Project of the Ghazi River

以盖孜河塔什米力克引水工程边坡为例,采用拉伸剪切法计算河道岸坡的稳定性情况,分析河水水位、涨退水速率与岸坡安全系数变化的关系。结果表明:随着水位的升高,该类型河道岸坡安全系数呈减小趋势,稳定性变差;退水速率越快,岸坡安全系数越低,涨水速率越快,岸坡安全系数越高;岸坡的稳定性是其自身岩土体强度与水位变化相互作用的综合结果。通过分析研究,可为类似工程案例提供参考借鉴。

Taking the slope of Tashilmicik Water Diversion Project of the Ghazi River as an example, the article calculated the stability of the river bank slope by the tensile shear method and analyzed the relationship between the river water level, the rising and falling water rate and the change of the slope safety factor. The results show that with the increase of water level, the safety factor of this type of river bank slope decreases and the stability deteriorates. The faster the water withdrawal rate, the lower the safety factor of bank slope, the faster the water rising rate, the safety factor of bank slope. The higher the stability of the bank slope is the combined result of the interaction between its own rock and soil strength and water level changes. Through analysis and research, it can provide reference for similar engineering cases.
