| 摘 要： | 分析那吉航运枢纽工程上游左岸边坡运行期出现不同程度塌方的原因,认为在涉水岸坡设计中应重视坡脚土体的稳定性、地下水位骤降,以及水流波浪对岸坡的冲刷和吸附作用。对塌岸段提出放缓边坡和水泥搅拌桩加固土体两个处理方案,通过对其在安全、施工、工程投资、工程影响等方面比较推荐了放缓边坡处理方案。

| Abstract: | Based on the analysis of the causes of the landslide problem in the upper reaches of the left bank slope of Naji navigation junction project,it is concluded that we shall pay attention to the stability of slope soil,the sudden drop of the groundwater level,as well as the erosion and adsorption of the bank slope.Two treatment schemes,i.e.slowing down the bank slope scheme and cement mixing pile reinforcement scheme,are put forward for the bank slope landslide.Comparing them in safety,construction,project investment and project effect,we recommend the slowing down bank slope schemed. |
