摘要

针对地震高烈度设防区的具体工程,详细介绍了高压注浆技术加固大直径混凝土灌注桩的施工工艺和质量事故预防措施,并通过静载试验和动力检测验证了其可靠性,达到了较好的效果。
On the basis of a specific engineering project,the construction technique of high pressure injecting and grouting used in the cast-in-place bored pile project as well as the quality accident precautionary measures were introduced.The reliability was tested and verified through a static loading test and dynamic test according to high seismic fortification intensity areas.A good resolution was achieved.
