【摘要】:巖溶地區(qū)地質(zhì)情況復(fù)雜,部分橋梁樁基礎(chǔ)位置常常處于溶(土)洞影響的范圍內(nèi),影響橋梁結(jié)構(gòu)安全,常規(guī)處理方法主要是通過加長樁基礎(chǔ)穿過不良地層或施工前預(yù)先處理,但對成樁后發(fā)現(xiàn)較大溶洞處理技術(shù)一直是橋梁技術(shù)難點(diǎn),結(jié)合實(shí)際工程研究,采用多孔高壓射流對成樁后發(fā)現(xiàn)的樁底溶洞進(jìn)行壓漿處理。
[Abstract]:The geological conditions in karst area are complex, some bridge pile foundation location is often in the range of dissolving (soil) hole influence, which affects bridge structure safety. The conventional treatment method is mainly through lengthening pile foundation through bad stratum or pre-treatment before construction. However, it is always difficult for bridge to find large caverns after piling. Combined with practical engineering research, the porous high pressure jet is used to deal with the grouting of caverns found after piling.
