<p>This article presents new results from field tests and numerical simulations regarding the performance of fully grouted piezometers under transient flow conditions. The field observations show that using low-permeability grout for piezometer installation ...

<p>Rock slope stability analysis can be applied for transportation systems such as highways and railways. Failure of rock slopes includes a variety of rock falls, landslides and general instability of rock slopes. This article is done in a rock slope which ...

A series of full scale tests have been undertaken to assess the performance of ground strengthening methods to improve seismic performance of liquefiable soils in the Christchurch area. The tests used sequences of explosive charges to simulate seismic shaking ...

<p>Laboratory tests are often used to understand dynamic soil behavior and to develop cyclic soil constitutive models. However, the loading paths in lab tests are different from those in the field, resulting in the inaccurate prediction of site response. An ...

This paper reports experiences of leachate addition in a buried vertical well surrounded by multiple piezometers (pressure transducers) over a 2-year period. Data on spatial distribution of pore water pressure in the surrounding waste in response to cumulative ...

We first review, in five sections, the external perturbations and their associated processes which can lead to landslide failure: i) increase of slope angle, ii) increase of load applied to the slope, iii) rise of groundwater level and pore pressure, iv) frost ...

Complex mathematical representation of shear surfaces and pore pressures.

Temperature increase in saturated porous materials under undrained condition leads to thermal pressurization of the pore fluid due to the discrepancy between the thermal expansion coefficients of the pore fluid and of the solid matrix. This increase in the ...

In this paper the corresponding physical phenomena of liquefaction are briefly described. Among them are: compressibility of soil skeleton, dilation, contraction, elastic versus plastic deformation, interaction between pore water and soil skeleton, compressibility ...

The prediction of liquefaction and resulting displacements is a major concern for earth structures located in regions of moderate to high seismicity. In this paper a numerical procedure is used in which both generation and dissipation of pore fluid pressure ...
