Centrifuge Laboratory\u00a0<\/strong><\/p>\n

Geotechnical Centrifuge is a convenient equipment for scaled physical modeling.\u00a0 A 5 g-ton Genisco centrifuge at UNH is suitable for seismic soil models, slope stability evaluation, seepage mechanisms and contaminant transport study, soil-structure interaction problems. An inflight hydraulic shake table enables the researcher to study the response of geotechnical systems under earthquake loads. Various types of container are available serving different research projects including several rigid containers and a laminar container. This lab is equipped with advanced measurement sensors including LVDTs, accelerometers, pore water pressure sensors, moisture content probes, and cameras, all being monitored and controlled through remote DAQ. The machine also equipped with four hydraulic slip rings to supply hydraulic oil to the shake table accumulators and also to provide fluid for potential infiltration tests. State-of-the-art miniature piezocones and also electric actuators are designed for in-flight penetration and in-flight\u00a0static and dynamic loading scenarios.<\/p>\n<\/article>\n\t\t\t\t\"cent1\"\n\t\t\t\t\"cent2\"\n\t\t\t\t\"shake_table\"\n\t\t\t\t\"laminar\"\n\t\t\t\t\"cent3\n\t

Geotechnical Laboratory\u00a0<\/strong><\/p>\n

The geotechnical laboratory is equipped with a cluster of advanced testing equipment suitable for characterization of soils. These facilities are particularly suitable for experimental research involving advanced modeling of the constitutive behavior of soils. This includes a cyclic triaxial cell suitable for cyclic triaxial or resilient modulus evaluation. The laboratory also contains an automated custom-made cyclic simple shear device with P- and S-wave measurements. The lab also hosts an\u00a0advanced custom-made torsional ring shear apparatus. An Instron loading machine is available for compression testing as well. In addition, Point Load apparatus is available for rock testing. The lab also contains California Bearing Ratio testing apparatus and falling weight deflectometer useful for pavement testing. A state-of-the-art flow pump system is designed for precisely controlling the flow rates during the suction-controlled testing of unsaturated soils. A full-scale shake table facility in structural lab can also be used for 1-g modeling of geotechnical systems and soil-structure interaction problems. Also, several field testing equipment\u00a0are housed in the geotechnical laboratory.<\/p>\n\t\t\t\t\"geo1\"\n\t\t\t\t\"ctx3\"\n\t\t\t\t\"rs1\"\n\t\t\t\t\"dss\"\n\t

Soils Laboratory\u00a0<\/strong><\/p>\n

The instructional soils laboratory hosts fundamental soil characterization facilities including standard soil classification equipment, simple shear apparatus, direct shear apparatus, triaxial cell setup which can be used for conventional triaxial tests (CU, CD, UU) as well as consolidation tests, consolidometers and flexible wall permeameter.<\/p>\n\t\t\t\t\"\"\n\t\t\t\t\"soils_1\"\n\t\t\t\t\"soils_2\"\n\t\t\t\t\"\"\n\t

Computational Facilities<\/strong><\/p>\n

General computer access is available through the Civil Engineering Student Computer Cluster. The computer cluster consists of 25 networked state-of-the-art PCs for undergraduate and graduate instruction and research. In addition, several high capacity servers are available in the department and throughout the campus for high performance computational efforts. Instructional and advanced engineering software are available for geotechnical-related projects such as Plaxis, Abaqus, LPILE, UT4, and Rocscience among other traditional engineering software.<\/p>\n\t\t\t\t\"\"\n\n","protected":false},"excerpt":{"rendered":"
