摘要

Seismic upgrades for San Pablo Dam include removal of the existing downstream buttress of the dam and construction of a new enlarged downstream buttress that is founded on alluvial/colluvial materials after they have been strengthened by Cement Deep Soil Mixing (CDSM). This paper describes the approach used to design the CDSM soil improvements, outlines the approach used for preparation of plans and specifications to implement the design, and summarizes the results of the quality control tests on the completed work. The value of the CDSM work was approximately $30 million and is believed to be the largest CDSM project completed in the United States to date.
