海相粘土(Marine Clay)作为软基的一种,具有低强度、高塑性的特点
本文以新加坡樟宜机场第三跑道项目明挖隧道工程为例,浅谈水泥深层搅拌桩在海相粘土层中的加固效果及其质量控制
关键词:水泥深层搅拌桩;海相粘土;质量控制 Abstract: Deep Cement Mix is used as a measure to strengthen the soft foundation of deep foundation pits and at the same time as a flexible support system
As a kind of soft foundation , Marine Clay has the characteristics of low strength and high plasticity
This article takes the open-cut tunnel project of the third runway project of Singapore Changi Airport as an example to discuss the reinforcement effect and quality control of the deep cement mixing pile in the marine clay layer
