摘　　要：淤泥质地层具有含水量高、孔隙比大、压缩性高、黏聚力小、承载力低、触变性强等特点,保证施工过程中管线与消能井结合部位的稳定性具有重要意义。以广州南沙区大岗镇农村生活污水治理查漏补缺工程为实例,通过采用ABAQUS有限元数值模拟软件精细仿真了穿越淤泥质地层段管网的施工过程,研究柔性管线与消能井结合部位变形特征及结构强度安全性,以便指导现场施工。Muddy formation is characterized by high water content,large pore ratio,high compressibility,small cohesion,low bearing capacity and strong thixotropy.It is of great significance to ensure the stability of the joint of pipeline and energy dissipation well during construction.Taking Dagang Town Rural Sewage Treatment Leak Checking and Deficiency Makeup Project in Guangzhou as an example,the construction process of pipeline network crossing muddy strata is simulated by ABAQUS finite element numerical simulation software,and the deformation characteristics and structural strength safety of the joint area of flexible pipeline and energy dissipation well are studied,so as to guide the construction on site.
