| 中文摘要: |
| 临近堤防的基坑开挖可能导致堤防渗透稳定性下降，增加堤防失稳的风险。以阜南县蒙洼中心水厂厂区淮堤段除险加固工程为例，分析了厂区实施过程中堤防加固的必要性，制定了基于高压喷射灌浆技术的截渗墙方案及措施。研究结果表明，临近堤防的厂区建筑物基坑开挖后，堤防的渗流量和最大出逸比降显著增加，渗透稳定性降低，高压喷射灌浆成墙的截渗措施可有效降低渗流量及出逸比降，确保堤防的结构安全。 |

| Excavation of foundation pits near embankments may lead to a decrease in the permeability stability of embankments, increasing the risk of embankment instability. This article combines the foundation pit construction project of Mengwa Central Water Plant in Funan County to analyze the seepage stability and anti sliding stability of the foundation pit slope of the Huaihe River Left Embankment. Based on high-pressure jet grouting technology, measures for anti-seepage wall engineering are formulated. The results show that using this seepage interception scheme significantly reduces the maximum escape ratio drop, which is smaller than the current seepage ratio drop of the embankment before excavation, and the seepage flow rate also drops below the current seepage flow rate of the embankment before excavation, ensuring the long-term stability of the embankment.
Keywords: embankment stability；seepage stability；anti-sliding stability；cut-off wall；high-pressure jet grouting. |
