| 中文摘要: |
| 深层搅拌法作为软土地基处理的一种方法在我国已经得到广泛应用。但在其施工过程中,常会由于冒浆、复搅深度、土体搅拌不均和外加剂选择不当等问题影响桩体强度和单桩承载力。在深层搅拌法施工过程中可以采用复搅法、喷搅法或合理选择外加剂来避免上述情况的发生,以提高桩体强度和单桩承载力。 |
| 英文摘要: |
| Deep-mixing method has been used widely in our country as a way of soft-soil treatment, but during the course of construction, the strength of the pile shaft is usually influenced because of the problems such as the mixed materal's returning to surface, the homogeneous degree of soil-mixing, additives and or soon. So in the course of the construction some way must be done to decrease occurrence of such phenomena. |
