Collapse Pressure Prediction for Thermoplastic Water Well Casings
This study analytically determined the collapse resistance of thermoplastic water well casings subjected to a linearly varying external pressure. The method used in the analysis was the principle of minimum potential energy, which is based on minimizing the strain energy of the casing, the potential energy of the external loads, and the strain energy of the confining medium surrounding the casing. The collapse pressure prediction equation was developed in terms of casing geometry, external loading conditions, casing material properties, and surrounding soil or grout support. Parametric studies were conducted to evaluate the influence of these parameters on the predicted collapse pressure. Results indicate that the current method used in designing thermoplastic water well casings in some cases underestimates the collapse resistance of the casing.
