Mount Olympus Tunnel; San Diego County, California, USA
Tasks Performed: Geotechnical consultant responsible for providing geological, geotechnical, and tunnel design services. His duties included the development and implementation of the subsurface exploration program to determine the design parameters and monitor the performance of this high-head pressure tunnel. He conducted geological and hydrologic studies; developed alternative tunnel alignments to minimize the potential of hydrofracturing and optimizing lining design; prepared detailed tunnel lining designs and cost studies which showed that approximately 6 kilometers of steel liner could be replaced by a more economical, unreinforced, prestressed concrete liner.
Duration: 1994 (12 months)
Description: The Mount Olympus Tunnel is a high-head pressure tunnel which is to be constructed as part of the San Diego Pipeline No. 6 Project, a 3-meter-diameter water conveyance system. The project is located near the city of San Marcos in northern San Diego County. The tunnel portion of the conveyance system is approximately 10-kilometers-long.
