摘  要：针对一处桩基无法进行干成孔，且上方及周围为高压带电区，提出了一种高压旋喷桩地基处理方式。采用高压旋喷桩双管法工艺，成桩效率高，克服了在复杂地质条件下塌孔严重和桩基质量不易控制的技术难题，而且机械设备较小、施工作业面较小、机械化程度高、经济环保。

Abstract： Aiming at the fact that a pile foundation cannot be drilled and there is a high-voltage electrified area above and around， a foundation treatment method of high-pressure rotary jet grouting pile is put forward. The double-pipe method of high-pressure rotary jet grouting pile has high pile forming efficiency， overcomes the technical problems of serious hole collapse and difficult pile foundation quality control under complex geological conditions， and has the advantages of small mechanical equipment， small construction surface， high degree of mechanization， economy and environmental protection.

Keywords： high groundwater level; foundation treatment; high pressure rotary jet grouting pile
