for specialist laboratory testing. Both of the above methods can produce holes to great depths, which can be used for in situ tests as well as for sampling, and can allow the installation of instrumentation (for example, to measure groundwater pressures). Probing is increasingly being used as a cheap alternative to boring and drilling.

The ground can be improved by adapting certain ground improvement techniques. Vibro-compaction increases the density of the soil by using powerful depth vibrators. Vacuum consolidation is used for improving soft soils by using a vacuum pump. Preloading method is used to remove pore water over time. Heating is used to form a crystalline or glass […]. The first in situ experiment in Alberta took place in , when a Pittsburgh-based outfit, the Barber Asphalt and Paving Company, drilled a bore hole into the bitumen and pumped in steam to liquefy the oil. The experiment failed. In the early s, other in situ experiments also took place, but none were commercially successful.

The overtest is one of several large-scale, in-situ experiments currently under construction near Carlsbad, New Mexico at the site of the Waste Isolation Pilot Plant (WIPP). Room B, a single isolated room in the underground salt formation, is to be subjected to a thermal load of approximately four times the areal heat output anticipated for a. Abstract.

SCKCEN started the construction of the existing facility 20 years ago, aiming at performing in situ research in the Boom Clay, a tertiary clay formation identified as a potential host rock for HLW. The in-situ experiments involve the radionuclides HTO, iodide, Am, Tc, inorganic carbon (H14CO3-) and organic carbon (14C-labelled organic matter).

The long-term lab experiments are/were performed with radionuclides (RN) which have the tendency to form “stable” complexes with natural organic matter (NOM) omnipresent in Boom Clay. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A deep tertiary clay formation, "Boom Clay", present under the Mol-Dessel nuclear site, was selected as a potential host formation for the disposal of high-level and long-lived radioactive waste (HLW).

An underground laboratory (HADES) has now been operational for more than 15 years. EXPERIMENTAL PROGRAM DURING THE CONSTRUCTION OF AN UNDERGROUND LABORATORY IN A PLASTIC CLAY LAYER AT M DEPTH1 R. Funcken*, R. Heremans**, P. Manfroy**, M. Mayence* and R.

Funcken, R. Heremans, P. Manfroy, M. Mayence, R. Vanhaelewyn. The Boom Clay was regarded as a potentially suitable host rock for a geological repository. As the Boom Clay is present underneath the technical domain of the SCK•CEN at Mol, SCK took the initiative for the construction of the HADES (insert link naar Hades onder facilities) underground research facility.

The Boom clay specimens were extracted at a depth of m in the Underground Research Facility (URF) of Mol, Belgium. As noted by Horseman et al. () and commented on by Burland (), the Boom clay is geologically lightly overconsolidated. However, the yield stress of Boom clay is larger than the pre-consolidation pressure owing to creep and.

Boom clay, a stiff clay, has been selected as a potential host formation for the geological disposal of radioactive waste in Belgium. The underground research facility HADES has been constructed to enable various in situ experiments to be performed on Boom clay so as to study the feasibility of high-level radioactive waste disposal, and to provide reliable data on the performance of Boom clay.

The research and development programme on geological disposal for high-level and long-lived waste (HLW) in Belgium was initiated in A deep tertiary clay formation, the Boom Clay, present under the Mol-Dessel nuclear site, was selected as a reference host formation for experimental purposes.

Future in situ experiments include a novel di-monopole experiment that allows in situ monitoring of matrix diffusion to be carried out and one to study diffusion from a shear zone using soluble, non-sorbing radionucide tracers is planned.

ISBN In the context of nuclear waste disposal in clay formations, laboratory experiments were performed to study at reduced scale the excavation damaged zone (EDZ) induced by the construction of galleries in the Boom clay formation. For this purpose, thick-walled hollow cylindrical samples were subjected (after recovery of in situ stress conditions) to a decrease in the inner confining pressure.

Abstract. The Belgian R&D programme on geological disposal for high-level and long-lived waste was initiated at SCK•CEN in A deep tertiary clay, the Boom Clay, was selected as a candidate host formation for experimental purposes, which led between and to the construction of the HADES underground laboratory at m depth (one shaft and two galleries with a total length of.

In this project. suction-controlled experiments have been performed on Boom clay (B), FoCa clay (Fr) and Almeria bentonite (Sp). The aim of these experiments is to test the validity of the interpretive model developed by Alonso and Gens (Alonso et al., ).

and to build a database of unsaturated clay thermo-hydro-mechanical parameters. 4 Construction of the “in situ” physical model at the Underground Educational Facility Josef The construction of the “in situ” model commenced in February and was completed in October Model design The model is made up of four rings each consisting of 8 segments and each of.

In this paper, a comparative modelling exercise from the DECOVALEX project is presented. The exercise is based on in situ experiments, performed at the Tournemire Underground Research Laboratory (URL), run by the IRSN (Institut de Radioprotection et de Sûreté Nucléaire), in France.

These experiments aim at identifying conditions (e.g. technical specifications, design, construction. • in-situ testing during the field exploration program; • laboratory testing, and • back-analysis based on site performance data The two most common in-situ test methods for use in soil are the Standard Penetration Test, (SPT) and the cone penetrometer test (CPT).

Section describes these tests as well as other in-situ tests. Geotechnical Special Publications (GSP) are the primary outlet of the Geo-Institute for continuing the tradition of geotechnical knowledge transfer. GSPs reflect the broad variety of geotechnical activities, ranging from proceedings of a specialty conference or annual Geo-Institute Congress to guidelines and special reports prepared by technical committees.Construction planning is more difficult in some ways since the building process is dynamic as the site and the physical facility change over time as construction proceeds.

On the other hand, construction operations tend to be fairly standard from one project to another, whereas structural or foundation details might differ considerably from one.
