Methodology And Process To Accompany A Virtual Geotechnical Database For The St. Louis Metropolitan Area, Katherine Leigh Onstad
Methodology And Process To Accompany A Virtual Geotechnical Database For The St. Louis Metropolitan Area, Katherine Leigh Onstad
Masters Theses
"The St. Louis metropolitan (STL) area, which spans Missouri and Illinois, currently has no overarching organization of geospatial data (geodata). The two states have their own geodata, using their own individual standards. The development of a virtual geotechnical database (VGDB) encompassing the entire STL area on both sides of the Mississippi River is a solution to the data sharing and standardization problem of this area. The VGDB integrates geodata from disparate sources into a geographic information systems (GIS) database accessible via the internet. The creation of the STL area VGDB consisted of three parts: 1) compiling the geodata; 2) formatting …

Imaging In Karst Terrain Using Electrical Resistivity Tomography, Iana Muchaidze
Masters Theses
"The Missouri Department of Transportation (MoDOT) plans to construct a new intersection between highway 60 and highway 65 to alleviate traffic congestion during peak flow periods. This construction site, which is referred to as the Route 60/65 study site in this thesis, is located on the southeastern side of Springfield, Greene County, Missouri. Bedrock in the study area (Burlington-Keokuk Limestone) is characterized by karstic features such as loosing streams, underground caves, and sinkholes. Prior to the commencement of construction, MoDOT conducted a study of the subsurface conditions in the Route 60/65 study site. The main objective was to identify features, …

Ground Motion Sensitivity Analyses For The Greater St. Louis Metropolitan Area, Ece Karadeniz
Masters Theses
"Local site effects can play an important role in modifying the intensity of ground shaking and earthquake damage. The process of rock motion propagating through the soil column can be approximated using one-dimensional site response analyses. To evaluate the likely site response several input parameters are required. These include: thickness of the unconsolidated soil cap, shear wave velocity, unit density, dynamic soil properties, and acceleration time histories. Considerable uncertainty often exists in regards to these input parameters. In this study, the program Shake2000 was employed for site response analyses and sensitivity analyses were performed to determine how the uncertainties in …
