Innovative laboratory testing

Three laboratory test techniques were developed to study and quantify damage development in loaded rock specimens and to provide data for use in the calibration and solution of numerical models. Damage-controlled tests involved incremental loading–unloading cycles with the stress at volumetric strain reversal (crack damage stress σ_cd) and elastic properties calculated for each successive cycle. Damage was quantified by measuring the irreversible volumetric strain upon unloading and the degradation of rock strength and elastic properties. In long-term loading tests, a creep stress greater than σ_cd was applied to the specimen until failure. The time to failure was dependent upon the ratio of the creep stress to σ_cd, and to confining pressure. It was shown that σ_cd is a reasonable estimate of the long-term rock strength. Damage was quantified by measuring the degradation of elastic properties through periodic unloading–reloading cycles. The test data were used for the calibration of Itasca's PFC stress-corrosion model. Five types of thermoporoelasticity tests were designed to determine seven of the nine thermoporoelastic parameters required for the modelling of the thermoporoelastic response of rock. Tests were performed by applying increments of confining pressure, temperature or pore pressure on the rock specimen, and measuring the changes in confining pressure, specimen volume and pore pressure. The measured values of five parameters were found to agree reasonably well with the estimated values.

Smoke inhalation: Clinical and laboratory studies

The increasing importance of smoke inhalational damage to the lungs has of recent years become clear to clinicians involved in the management of fire victims. Earlier identification of those patients at risk is essential so that appropriate therapy can be instituted, and it is now clear that close co-operation with the Fire Service is invaluable when detailing the case history of victims at the time of hospital admission. To this end a prepprinted questionnaire type of case-sheet has been prepared to aid the clinician.In addition to a thorough clinical examination and continuing close observation in an intensive care unit, laboratory assay of the carboxyhaemoglobin level has been shown to be of assistance in the confirmation of the diagnosis. The present studies in Glasgow Royal Infirmary have also demonstrated the close correlation between the ‘corrected’ carboxyhaemoglobin level and the presence of cyanide in the patient's blood. A large cohort of fire survivors is currently being followed up to identify any significant residual pulmonary damage.

Visualization and quantification of soil laboratory impact compaction

As important methods to guide the field soil compaction, the standard and modified Proctor tests for laboratory compaction have remained unchanged for decades, which should be improved to better understand the compaction process and the properties of soils. In this study, an accelerometer was installed on a Marshall impact compactor to capture the dynamic response of three types of soils during compaction. The experimental test results indicated that the acceleration curve for each blow gradually evolved to a stable pattern following the progress of compaction, and the impact and gyratory locking points were linearly related with coefficient of determination R² equal to 0.59. The impact compaction curve could be further constructed by filtering the structural resonance, which can be used to quantify the compactability of soil materials. Although each type of soil had a unique set of compaction curves, the slope and value of compaction curve altered accordingly as the moisture content changed for the same soil. In addition, the average acceleration value at the final compaction stage could serve as the target value of soil stiffness.
