三峡水库运行条件下兰陵溪场镇库岸边坡稳定性分析

根据三峡库水位调控方案，在分析库水位变化与岸坡稳定性的一般规律的基础上，对兰陵溪场镇库岸边坡稳定性进行定性分析，并采用传递系数法计算四个剖面在不同工况条件下的稳定性系数。结果表明：蓄水时，各实测剖面的稳定性均下降，发生局部岸踏的可能性自北向南逐渐增大；汛期防洪库水位从高程175m降为145m时，稳定性最差，极有可能发生整体性塌岸事故。因此，只有在水位骤降这种极限状态下保持稳定，才能确保兰陵溪场镇库岸边坡的安全，这对边坡防治以及水库安全运营提供了科学依据。

Slope Stability Analysis beside Lanlingxizhen Reservoir under the Condition of SANXIA Reservoir Running

According to the controlled method of the water level of the Sanxia Reservoir,the article is based on the common regulation between the water level variety and slope stability,qualitatively analyzes the slope stability beside the Lanlingxizhen reservoir and takes the passing coefficient to calculate the stability value of the four sections under the difficult construction conditions.The results shows that the stability of the real measured section is all dropped down while sluicing,the possibility of some p...
