由于高压注浆桩施工环节多、工艺尚不完善等原因，在实际施工的各个阶段中经常会遇到一些工程问题。文中列举了此类桩基础在成孔阶段和成桩阶段容易发生的问题，例如：孔斜、局部缩径、塌孔以及桩顶混凝土疏松、夹泥砂、桩身断层等，并且针对上述问题提出了在各个施工环节上应注意的事项以及发生工程问题时的处理措施。 Due to the high number of high-pressure grouting piles and the fact that the process is not yet perfect, some engineering problems are often encountered in various stages of actual construction. The problems that such pile foundations are prone to occur in the hole formation stage and the pile formation stage are listed in the text, such as: hole slanting, local retraction, collapse holes, loose concrete at the top of the pile, sand inclusions, pile faults, etc., and are proposed for the above problems. Matters needing attention in each construction process and treatment measures when engineering problems occur.
