Abstract

Accurate assessment of material properties is essential for a meaningful evaluation of the dynamic behavior of a dam. Comprehensive studies using in- situ measurement and laboratory testing techniques coupled with back calculations of dam responses in recorded motion gives the following conclusions : (1) Response in good agreement with actual motion can be obtained by using appropriate analytical models and material properties; (2) a laboratory test may give reasonable result, but allowance should be made for the effects of strain level, sample disturbance and reconsolidation, especially in loose, non - cohesive soil; (3) in- situ shear wave velocity measurement is considered to be the most representative technique and gives the best estimation in Gmax.

Assessment of Dynamic Properties of Wushantou Dam

St. Louis, Missouri

Accurate assessment of material properties is essential for a meaningful evaluation of the dynamic behavior of a dam. Comprehensive studies using in- situ measurement and laboratory testing techniques coupled with back calculations of dam responses in recorded motion gives the following conclusions : (1) Response in good agreement with actual motion can be obtained by using appropriate analytical models and material properties; (2) a laboratory test may give reasonable result, but allowance should be made for the effects of strain level, sample disturbance and reconsolidation, especially in loose, non - cohesive soil; (3) in- situ shear wave velocity measurement is considered to be the most representative technique and gives the best estimation in Gmax.
