振冲碎石桩在粘性土地层中的施工尝试

Construction Attempting for Vibro-Replacement Crushed Stone Columns in the Cohesive Soil Layers

振冲碎石桩在加固粗颗粒、无粘性土地层,提高地基承载力方面已得到了广泛的应用,但在利用振冲碎石桩处理回填土中粘性软弱土层方面的应用还存在一定的施工难点。本文结合工程实践的效果,详细地介绍了如何避免粘性软弱土层对振冲碎石桩施工带来的不良影响所采取的一系列工程措施,为粘性软弱土层的工程处理提供了可借鉴的经验。

Vibro-replacement stone column in the reinforcement of coarse particles and the non-cohesive soil layers improving the foundation bearing capacity has been widely used, but it is still a difficult construction that applicating vibro-replacement stone pile reinforced the cohesive soft soil layers of backfill. The text introduces how to avoid the bad effects that the cohesive soft soil layers of backfill bring to vibro-replacement stone column while being constructed and it provides the referable experience for the engineering handle of the cohesive soft soil layers.
