In Situ Shear Wave Measurements for Evaluating Dynamic Soil Properties at the Bannister Federal Complex, Kansas City, Missouri
An in situ geophysical investigation consisting of crosshole and downhole shear wave (S-wave) seismic cone penetrometer tests (SCPT) was performed at the Bannister Federal Complex (BFC) located in Kansas City, Missouri. The SCPT was also used to collect cone tip resistance and sleeve friction data to aid in characterizing the soils at the site. The results of the SCPT were used to provide a continuous prediction of soil type and N-values. The main purpose of the investigation was to determine the S-wave velocities of the soil and bedrock in the vicinity of the main building at the BFC. This information will be used to perform a dynamic analysis of the building and its foundation. The results of the dynamic analysis will be used to determine if any building design modifications are required. The S-wave velocities measured for the clay materials (alluvium) using the crosshole and SCPT methods agreed very well. The S-wave velocities in the clay material increased with depth and ranged between 350 and 775 fps. A 1- to 5-ft. thick basal clay-gravel, which overlies bedrock, showed a velocity of approximately 1,100 fps. The Pleasonton Group bedrock found at the site is a hard shaly siltstone and is encountered at a depth of approximately 40 ft. The bedrock exhibited an S-wave velocity of approximately 1,900 fps and was measured using the crosshole S-wave method. (MM).
