Hydraulic Conductivity Of Environmentally Controlled Landfill Liner Test Pad, Camila Maldonado Soria Galvarro
Hydraulic Conductivity Of Environmentally Controlled Landfill Liner Test Pad, Camila Maldonado Soria Galvarro
Civil Engineering Undergraduate Honors Theses
Laboratory and field hydraulic conductivity tests have been conducted on soil samples to develop and verify the zone of acceptance for liner placement. Compaction testing and flexible wall hydraulic conductivity tests were performed on fifteen (15) samples to determine the dry unit weight, molding water content, and laboratory permeability. Five of the fifteen samples were compacted at Standard proctor energy, five were compacted at 75 percent of Standard proctor energy, and five were compacted at 50 percent of Standard proctor energy. The results obtained from the laboratory portion of the testing program (the zone of acceptance) are presented. A ten …
Effects Of Piston Uplift, Piston Friction, And Machine Deflection In Reduced Triaxial Extension Testing, Morgan Race
Effects Of Piston Uplift, Piston Friction, And Machine Deflection In Reduced Triaxial Extension Testing, Morgan Race
Civil Engineering Undergraduate Honors Theses
A series of Reduced Triaxial Extension (RTE) tests were conducted on dummy (brass) and null (water) samples to determine the effects of (corrections required for) piston uplift, piston friction and system compliance associated with RTE tests. During the consolidation stage of RTE tests, the sample may be consolidated in isotropic or anisotropic stress conditions. During the shearing stage of an RTE test, the sample is unloaded in the axial direction by decreasing the deviator stress while the radial stress remains constant. Ten (10) tests were conducted on a brass "dummy" sample. The device was assembled in the same manner as …
Two Dimensional Modeling Of Wind Effects On A Bridge Section Using Finite Difference Method, Jessica Carreiro
Two Dimensional Modeling Of Wind Effects On A Bridge Section Using Finite Difference Method, Jessica Carreiro
Civil Engineering Undergraduate Honors Theses
Wind effects on long span bridges are a major concern for bridge design. Wind acts as a dynamic load on the bridge deck causing the bridge to react in ways not accounted for in static load design. Attention to these effects increased tremendously after famous bridge collapses, such as the Tacoma Narrows Bridge in 1940. Due to this collapse and others, engineers were made painfully aware that wind phenomena, such as flutter and vortex shedding, can cause major structural damage if not considered in the design process. The solution for many years since has been to conduct wind tunnel tests …
