Chalmers Publication Library (CPL) offers the possibility of retrieving research publications produced at Chalmers University of Technology. It covers all types of publications: articles, dissertations, licentiate theses, masters theses, conference papers, reports etc. Since 2006 it is the official tool for Chalmers official publication statistics. To ensure that Chalmers research results are d...
the effects of cementation and the physical properties of grains on the shear behavior of grouted sands are investigated in this paper. the consolidated-undrained triaxial shear behavior of three grouted carbonate sands with different physical properties, including particle size distribution, particle shape and void ratio, was studied. two sands were obtained from the north shores of the persia...
One type of seepage water that is difficult to plug by grouting the exuding through pores sandstone in deep underground engineering. Aiming at this problem, paper collected deep-mine samples from Southwest Shandong coalfield, studied pore structure and its influential factors casting thin slices, scanning electron microscopy, mercury intrusion physical property tests, selected five representati...
In order to investigate the fracturing of the bedrock and its possible heterogeneous distribution in situ, four boreholes equipped with double-U geothermal pipes of 100 m long were installed on the campus of the University of Liege (Liege, Belgium) over a surface area of 32 m2. The bedrock, which starts at a depth approximately of 8 m, is quite fractured and consists mainly of siltstone and sha...
