Abstract
In July 1991, the intake and discharge pipelines of a major power plant collapsed. A 60-ft. deep excavation adjacent to several structures sensitive to ground movements was required- for remediation. Based on conventional analyses, the estimated factor of safety against base heave was close to 1. 0 for the required excavation, and there was grave concern for damage to appurtenant structures. A viable reconstruction scheme was developed through the integration of finite element analyses and construction monitoring.

Braced Excavation at the NIPSCO Bailly Station Power Plant
St. Louis, Missouri
In July 1991, the intake and discharge pipelines of a major power plant collapsed. A 60-ft. deep excavation adjacent to several structures sensitive to ground movements was required- for remediation. Based on conventional analyses, the estimated factor of safety against base heave was close to 1. 0 for the required excavation, and there was grave concern for damage to appurtenant structures. A viable reconstruction scheme was developed through the integration of finite element analyses and construction monitoring.
