关于深层搅拌桩桩体强度及单桩承载力的分析与探讨

Analysis and research on the factors influencing pile shaft strength and bearing capacity of deep-mixing pile

通过分析深层搅拌法在处理软土地基施工过程中出现的冒浆、复搅深度不合理、土体搅拌不均和外掺剂选择不当等影响桩体强度和单桩承载力的影响因素,探讨了如何提高深层搅拌桩桩体强度和单桩承载力的措施。

By analyzing the influences of such factors as flow-up of grout, irrational remixing depth, uniformity of soil-mixing and improperly selected additives on pile shaft strength of deep-mixing piles and bearing capacity of single pile, the paper discusses the measures of improving pile shaft strength and bearing capacity of single deep-mixing pile.
