摘要
经过对洛湛铁路DIK47+794.93五里牌立交大桥3号墩桩基础溶洞处理,针对溶洞较发育地区桩基础设计施工特点,结合现场桩孔施工钻探情况,弄清桩位处地质和溶洞情况,调整设计和施工方法,既加快了施工进度,又确保了结构安全,同时也节约资金。
Through treating Karst caves of No.3 pile foundation for Wuli Pai Railway Overpass at DIK47＋794.93 of Luoyang-Zhanjiang Railway,the design and construction methods are adjusted,aiming at design and construction characteristics of pile foundation at typical Karst areas,combined with onsite pile hole drillings.It not only speeds up construction schedule,but also enhances structural safety and economizes the use of funds.
