EQE 585- Site Improvement Methods To Mitigate Earthquake Effects
COURSE NO AND TITLE : EQE 585– Site Improvement Methods To Mitigate Earthquake Effects
- to learn the types of soil improvement techniques available for mitigation of geotechnical hazards
- to apply the soil imptovrement methods to the existing structures, pipelines, and other constructed facilities under seismic condions.
- to improve the liquefiable soils to mitigate seismic hazards, and
- to measure the effectiveness of soil improvement by laboratory, in situ, or geophysical tests.
Weeks |
Topics |
1 |
Introduction to Geotechnical Engineering (Basic earthquake effects, local site effects and ground motions, seismic hazards (Structural hazard, liquefaction, landslides, retaining structure failures, slope stability, lifeline hazards). |
2 |
Site investigation for geotechnical earthquake engineering. Properties of dynamically loaded soils (laboratory and field tests). |
3 |
Liquefaction (Evaluation of liquefaction hazards, liquefaction susceptibility, effects of liquefaction (alteration of ground motion, development of sand boils, settlement, instability) and alternative methods to mitigate the liquefaction hazards. |
4 |
Classification of ground modification (Techniques, suitability, feasibility, and durability). |
5 |
Densification techniques (vibro techniques; dynamic compaction, blasting, compaction grouting, etc.) and applications. |
6 |
Reinforcement techniques (Stone columns, Compaction piles, Drilled inclusions) and applications. |
7 |
Grouting and mixing techniques and applications. |
8 |
Modification by admixtures (Lime, tire waste, fly-ash, microbially induced cementation, etc.) and applications. |
9 |
Drainage techniques. Design of dewatering systems (Excavations and Slopes). Preloading and the use of vertical drains. |
10 |
Geosynthetics for earthquake hazard mitigation (soil reinforcement, soil isolation, retaining walls, slope stabilization, embankments, foundations, unpaved roads, railroads, etc.) |
11 |
Ground response analyses (One dimensional ground response analysis). Soil structure interaction (Illustration of soil-structure interaction effects and methods of analysis). |
12 |
Verification of soil improvement (Laboratory testing techniques, In- situ testing techniques, geopyhsical testing techniques) |
