目前国际上对于桥墩滑坡倾斜采取的补救措施是用钻孔灌注桩施工法(ICOS)加固桥梁基础。我国是用化学灌浆帷幕挖孔桩加固偏沉桥墩。这两种方法都只能维持桥墩短时间使用。对倾斜桥墩基础采用钻孔灌注桩施工法等补救措施,没有将倾斜桥墩产生的破坏性内力解除,反而在倾斜桥墩继续使用中,钻孔灌注桩的应力状态和地基反力同外荷载压力对整个桥墩的破坏性内力增大,其好处只是防止了桥墩的继续滑坡。
At present, the international remedy for the abutment landslide slope is to reinforce the bridge foundation with the bored pile construction method (ICOS). China is using chemical grouting curtain digging piles to reinforce the partial sink pier. Both of these methods can only maintain the piers for a short period of time. On the other hand, in the continuous use of inclined piers, the stress state of bored piles and the reaction force of foundation with the external load pressure The destructive internal forces increase the piers, the benefits only to prevent the continued decline of piers.
