Robust Earthquake Site Classification Assessment At Ontario Bridge Sites., Alex Bilson Darko
Robust Earthquake Site Classification Assessment At Ontario Bridge Sites., Alex Bilson Darko
Electronic Thesis and Dissertation Repository
Canadian seismic design guidelines classify subsurface ground conditions based on the average shear-wave velocity (VS) of the upper 30 meters (VS30). We seek to optimize a robust earthquake site classification procedure for Ontario bridge sites, assessed primarily from blind comparison of non-invasive VS depth profiling techniques. Non-invasive seismic testing is performed at 10 bridge sites in southern Ontario co-located with invasive penetration and/or borehole VS measurements. Non-invasive surface wave dispersion and site amplification functions are jointly inverted to retrieve VS profiles at each site. A general correlation between corrected VS and cone …

Monotonic Stress-Strain Behaviour Of Fibre Reinforced Cemented Toyoura Sand, Muhammad Safdar
Electronic Thesis and Dissertation Repository
The Great East Japan earthquake of 2011 generated a huge quantity of disaster waste and tsunami deposits, which required proper treatment and disposal. To effectively use these waste soils in geotechnical applications, it is essential to understand the mechanical behaviour in their native (pure) or mechanically stabilized form (amended with cement and fibre). To address these objectives, a series of monotonic stress-strain (e.g. compression and extension) triaxial drained and undrained tests were performed on pure Toyoura sand and mixtures of Toyoura sand-silt-cement-fibre. Additional laboratory studies were performed to investigate other related aspects, such as density, back pressure, small-strain elasticity, curing …

A Study On Chemical Grouting Of Quartz Sand, Bingfeng Xue
Electronic Thesis and Dissertation Repository
Chemical grouting has been used in engineering projects for decades. The primary objectives of chemical grouting in geotechnical engineering projects are to increase the soil strength, to decrease the soil permeability, and to control deformations of in-situ soil. In the design and applications of chemical grouting, laboratory testing of chemical grouted samples is an important step for the feasibility assessment.
The advantages of sodium silicate grout include high penetrability, flexible set times, and environmentally friendly, which makes it one of the most employed grouts in applications. Recently, an innovative sodium silicate, which has the silica to alkali ratio of 4.5 …
