黄土坡滑坡区临江崩滑体塌岸预测与防治

Prediction and Control of Bank Collapse at Landslide Areas of Loessic Slope

由于地质条件较差 ,黄土坡滑坡区临江崩滑堆积体曾发生多次小规模的滑塌 ,造成了重大人员伤亡和经济损失。在三峡库区蓄水后 ,影响库岸稳定的不利因素增加 ,如果临江崩滑堆积体得不到及时治理 ,一旦滑塌 ,后果将十分严重 ,崩滑体塌岸可能会影响到黄土坡滑坡区的整体稳定。为此 ,笔者根据塌岸成因的探讨 ,重点分析了塌岸的形成机制 。

Due to poor geological conditions of the sediments at landslide areas of loessic slope along the Yangtze River, small scale collapses have happened many times resulted in heavy casualties and economic losses. Once the Three Gorges Reservoir begins to store water, defective factors influencing the stability of the bank will increase. If these sediments could not be controlled on time, consequences would be disastrous and the overall stability of the landslide areas of loessic slope might be affected. In accordance with the causation of bank collapse, the formation mechanism is analyzed, and relevant preventive measures are proposed.
