In this study, shaking table tests are performed to investigate the behavior of excess pore water pressure in different soft soil-foundations of soil-structure interaction (SSI) system. The variation of the behaviors under cycled minor shock is observed. Moreover, The generation and variation mechanism of excess pore water pressure under earthquake excitation in different soft soilfoundations a...

Based on the optical deflection method, the resonant characteristics of a microcantilever under various pressure have been observed at room temperature to understand the pressure-dependent dissipation effect. Especially, the quality factor of the cantilever has been measured for up to fourth harmonic mode of cantilever resonance as a function of pressure between 0.1 and 1000 Torr. By considerin...

In this study, a grain-scale modelling technique has been developed to generate the capillary pressure-saturation curves for swelling granular materials. This model employs only basic granular properties such as particles size distribution, porosity, and the amount of absorbed water for swelling materials. Using this model, both drainage and imbibition curves are directly obtained by pore-scale...

A concentration difference of particles across a membrane perforated by pores will induce a diffusive flux. If the diffusing objects are of the same length scale as the pores, diffusion may not be simple; objects can move into the pore in a configuration that requires them to back up in order to continue forward. A configuration that blocks flow through the pore may be statistically preferred, ...

The consolidation of clay layers is great significance for groundwater environmental protection, storage utilization, and land subsidence. In this study, the governing equation excess pore water pressure during non-linear process under load conditions obtained based on one-dimensional theory. Analytical solutions are then derived with single or double drainage caused by dissipation pressure. Wi...

Abstract This paper presents a framework for modelling the random variation in permeability cement-admixed soil based on binder content and thereby relating coefficient of to unconfined compressive strength clay. The strength–permeability relationship was subsequently implemented finite element method (RFEM). effects spatial both clays RFEM is illustrated using two examples concerning one-dimen...

Abstract Slow earthquakes follow a power‐law size distribution with an exponential taper for the largest events. We investigated changes in of shallow tectonic tremor events during two prolonged episodes (>1 month) along Nankai trough and found that slope distributions increased while cut‐off magnitudes decreased late each episode, as activity waned. Interpreting these two‐dimensional probab...

Capillary pressure (Pc) curves acquired using the Magnetic Resonance Imaging (MRI) technique, call GIT-CAP, have 70-100 data points. This extra data, when compared with traditional porous plate or centrifuge techniques, allows for the interpretation of more information from the Pc curve. In particular, the pore throat size and relative permeability can be extracted. The pore throat size can be ...
