摘要
桩基加固是处理不良地基的重要方法之一,其对改善地基的变形稳定性意义重大。就此以四川康定金元水电站为例,对坝基存在的软弱地基问题提出基于振冲碎石桩加固的对策,同时对振冲碎石桩布置方案及主要施工工艺进行阐述,并进行效果评价。结果表明:经振冲碎石桩加固后,不良地基得到有效处理,坝基能满足工程建坝要求,相关处理方案与施工技术可为类似工程提供借鉴与参考。
Pile foundation reinforcement is one of the important methods for dealing with poor foundations,and it is of great significance for improving the deformation stability of the dam foundation.In this regard,taking the Jinyuan Hydropower Station in Kangding,Sichuan province as an example,the research proposes countermeasures based on vibroflotation gravel pile reinforcement of the foundation for some weak foundation problems existing in the dam foundation.At the same time,the layout plan and main construction technology of vibroflotation gravel piles are elaborated and evaluated.The results show that after reinforcement by vibroflotation gravel piles,the poor foundation is effectively treated and controlled,and the dam foundation can meet the requirements for dam construction.The relevant treatment plan and construction technology can provide reference for similar projects.
