The service life of rigid sewer pipes is often controlled by joint integrity. Leaking joints can cause ingress of water and develop voids where surrounding soil has eroded. The influence of soil voids on the stability of buried rigid pipes is investigated, considering the effects of void size, void location and void shape. A series of simplified void geometries are defined, and their influence on bending moments in the rigid sewer is studied through finite element analysis. Elastic analysis… Expand
Impact of soil erosion voids on reinforced concrete pipe responses to surface loads
Abstract This paper discusses the results of controlled, full-scale laboratory experiments on 0.9 m (36 in.) internal diameter reinforced concrete pipes (RC pipes) in the presence of simulatedExpand
Evaluation of defective sewer pipe–induced internal erosion and associated ground deformation using laboratory model test
Sinkholes induced by long-term internal erosion around defective sewer pipes have been widely reported. There is a need for an efficient method to understand the influence of pipe defects on internalExpand
Physical Modeling on Sand Erosion around Defective Sewer Pipes under the Influence of Groundwater
AbstractThis paper studies soil-erosion problem around cracked sewer pipes, which is usually associated with groundwater infiltration in sewer systems. Four factors (soil-particle size, defect size,Expand
Effect of Bedding Compaction on the Behavior of Buried Plain Concrete Pipes
Plain Concrete pipes serve as effective underground infrastructure lines especially as sewer lines and culverts. The installation quality has a high effect on the performance of the buried pipe-soilExpand
An approximate solution for two-dimensional groundwater infiltration in sewer systems.
An approximate solution for steady-state groundwater infiltration into sewer systems through line defects is presented and the infiltration rate is found to be controlled by the hydraulic conductivity of the surrounding soil and the total hydraulic head above the sewer pipe. Expand


Centrifuge modelling of the effects of soil loading on flexible sewer liners
This paper presents an experimental study of the effects of soil loading on large-diameter, close-fitting, non-bonded, flexible sewer liners as typified by ‘cured-in-place pipes’ (CIPP). CIPP is theExpand
