摘要
三峡库区库岸失稳现象频发,由于库水位在145~175 m之间频繁变化,且回填砂土渗透性大的特点,护坡工程基础快速施工技术成为迫切需要的关键技术。以秭归县茅坪镇滨湖路库岸边坡为例,进行了稳定性分析和灾害治理,工程中运用微型桩固结灌浆地基处理技术作为防治措施,有效地解决了施工技术问题。
There are many geological disasters result from reservoir bank instability happened in the Three Gorges Reser- voir Region. Due to frequent changes of the reservoir water level from 145 m to 175 m, and the large permeability of back- fill sand, the rapid construction technology of slope protection engineering has become the urgent need and key point. The authors take Binhu Road bank slope, located in Maoping Town of Zigui County, as an example for stability analysis and disaster prevention. In this project, the micro pile consolidation grouting foundation treatment technology has been pro- posed as a preventive measure which can effectively solve the problem.
