三峡库区柑子溪桥头库岸塌岸预测

三峡库区柑子溪桥头库岸段为土质岸坡。依据分段原则，将该库岸塌岸类型分为冲蚀磨蚀型和滑移型。对库岸稳定性评价，结果表明，3-3、4-4、5-5剖面在工况6情况下处于欠稳定状态，其他工况情况下处于稳定~基本稳定状态。

PREDICTION OF GANZIXI BANK COLLAPSE IN THE THREE GORGES RESERVOIR AREA

This investigates and analyzes the geological environment conditions of Ganzixi bank in Three Gorges reservoir area. It points out the typical of bank is an earthy one. According to some principles, the typical collapses of the bank can be classified into (1) washing and abrasion type and (2) slope type. At the same time, the paper also discusses the methods of getting forecasting parameters, calculates the stability of the land in the different cases. The results show that three engineering geological cross-sections are less stable in the case 6, but stable in other cases. The scope of bank collapse prediction is in line with the actual data. 
