摘　　要：以佛山海寿围堤防加固项目作为研究对象,针对工程的部分堤段不均匀沉降现象,土坝的密实度和部分段管涌的现状,在工程地质条件分析的基础上对场区内的特殊性土、堤身和堤基土的渗透稳定提进行综合评价,提出了充填式灌浆加固的主要治理建议,分险段和非险段提出了两种灌浆孔的布设方案,针对线性堤防工程提出了高效能的履带式多排灌浆的工艺方案,有效评估了西江流域海寿围堤防的稳定性情况。This paper takes the Foshan Haishou Embankment Reinforcement Project as the research object.Based on the analysis of engineering geological conditions,a comprehensive evaluation is conducted on the seepage stability of special soil,embankment body,and foundation soil in the site,in response to the phenomenon of uneven settlement in some sections of the project,the compactness of the earth dam,and the current situation of piping in some sections.The main governance suggestions for filling grouting reinforcement were proposed,and two grouting hole layout schemes were proposed for dangerous and non dangerous sections.A high-efficiency tracked multi row grouting process scheme was proposed for linear embankment engineering,effectively evaluating the stability of Haishou Embankment in Xijiang River Basin.
