The influence of selected factors on the load capacity of sewers that are renovated using the relining method

Abstract

The paper contains the results of a lengthy analysis of the operation of sewers renovated using the relining method. The author based the analysis on the effects obtained from computer simulations that were carried out using the Finite Element Method. The models used to proceed with the FEM simulations were verified by the results obtained from 1:1 laboratory research, conducted by the author over the period 2011-2013. The influence of a few strictly defined factors, related to the cooperation between the liner, injection grout and the construction of the original pipe, were taken into consideration. The report contains the description of FEM simulations and their assumptions, as well as a synthetic analysis of the results.
