Abstract

Earth and rockfill dams became popular in the 1960's primarily because of increased heights of dams, poor foundation conditions that rule out concrete dams, and vast improvements in excavation and vibratory compaction equipment. Such equipment made excavation and processing of rock and placement of rockfill much more economical than in the past. Due to the unique composition and the critical zone construction of earth and rockfill dams, they are subject to different types of problems. Some problems may be discovered and corrected during construction. Such problems cause changes in contract documents and delays in work, as in the case of Bay Springs Dam on the Tennessee-Tombigbee Waterway. Other serious problems may cause complete failure of the embankment, as in the case of Teton Dam in Idaho which failed in 1976. This paper presents a case history of problems that were experienced during the construction of Bay Springs Lock and Dam, Figure 1.

Construction Problems with an Earth and Rockfill Dam

Earth and rockfill dams became popular in the 1960's primarily because of increased heights of dams, poor foundation conditions that rule out concrete dams, and vast improvements in excavation and vibratory compaction equipment. Such equipment made excavation and processing of rock and placement of rockfill much more economical than in the past. Due to the unique composition and the critical zone construction of earth and rockfill dams, they are subject to different types of problems. Some problems may be discovered and corrected during construction. Such problems cause changes in contract documents and delays in work, as in the case of Bay Springs Dam on the Tennessee-Tombigbee Waterway. Other serious problems may cause complete failure of the embankment, as in the case of Teton Dam in Idaho which failed in 1976. This paper presents a case history of problems that were experienced during the construction of Bay Springs Lock and Dam, Figure 1.
