alluvial land

The weighting soil layer constructed at downstream toe of dike built on thick alluvial foundation is an effective measure for preventing the foundation from blowout failure.

盖重压渗是深厚型冲积地基堤防的主要渗流控制措施。

Many mining engineering subjects are established on geologic condition of alluvium.

因此开展冲积地层的开挖与支护设计及工程决策研究，对于推进该领域的理论和技术，探索一般工程决策的普遍规律和研究方法，掌握工程决策的内容、步骤和行为，指导矿业工程学科领域内的工程建设，具有较高的工程价值和应用前景。

In this paper, according to the characteristics of the typical subsoil in the alluvium area of Yellow River, the traditional Deep mixing method was studied, and the improved technique of Two-jetting & four mixing method was successfully applied to the engineering practice.

结合工程实例 ,针对黄河冲积地区典型地层 ,经过研究探讨 ,将传统的深层搅拌桩施工工艺改进为“二喷四搅”工艺流程 ,在实际的工程施工中取得了良好的效果 ,对该地区深层搅拌桩的施工具有重要的指导作
