Retrofitting Drainage Systems with Pressed-In Sheet Piles in Very Hard Soil of Southern California
Takefumi Takuma, Christopher DellAringa and Masashi Nagano

Multiple agencies in Southern California are retrofitting and upgrading their levees to catch up with ever-advancing urbanization affecting the requirements for existing channels and levees in this seismically active zone. Pressed-in sheet piles have been specified on some of these projects to minimize noise and vibration problems associated with sheet pile installation. This paper will study three Southern California levee and sewer pipeline retrofit projects that utilized pressed-in sheet piles in hard soil conditions with N-values higher than 50.
