The new boring, numbered FR 214-956, was cored with triple core barrel and every half meter a sample was taken to determine the water content. In order...

On non- durable slaking rock material such as coal measure rock, water as water content in pore space will control the oxygen diffusion and slaking, thus oxidation rate of sulfide mineral contained in rock.

The measured water mass balance and observation of relative humidity, water content, liquid pressure and relative displacements have been adequately reproduced. The simulation achieves a close quantitative agreement...

The saturated water content of the siltstone provides a useful quantitative indicator of the engineering properties...

The equations of state deduced from these measurements are expressed in a p-J1 formalism where ~p/p -1 is the rate of compression (Figure 3). The Armor model can take. into account the paths of .Ioading in c~mpression...

It has been recently recognised that the tunnels in expansive ground was mainly due to the squeezing of surrounding media. Therefore...

With decreasing water content the cataclastic deformation regime changes from affecting single clay minerals to aggregates. Generally, shales aggregates are deformed by visible joints and faults...

Based on the data of triaxial creep test, two nonlinear rheological models are recommended for the shales. To calculate the time-dependent formation load on the oil well...

... alternative quantitative method was used. As discussed by Johnston and Chiu (1982), the saturated water content, w o, represents a simple and quantifiable parameter which reflects the degree of weathering. The range of water contents concerned in this investigation varied between about 4% (slightly weathered...
