通过工程实例,介绍了应用高压旋喷注浆法处理旋挖灌注桩桩端沉渣,同时用钻芯法检测评价了加固处理效果,为类似工程事例提供参考。 Through engineering examples, the application of high pressure rotary jet grouting method to treat the settlement of pile end of rotary-driven bored pile is introduced. At the same time, the effect of reinforcement treatment by the core-drilling method is evaluated, providing reference for similar engineering cases.
