Study on Dynamic Properties of Saturated Clay and Undisturbed Silty Clay

2009
The testing is employed to perform cyclic torsional shear test under isotropic consolidated condition. The authors conducted three dynamic torsional with single sample achieving dynamic properties under three confining pressures with saturated clay and undisturbed silty clay in Dalian.

Freezing-Thawing on Dynamic Characteristics of Silty Clay

2020
The subway, which boomed in more and more cities, has been considered as a significant way to solve the urban traffic problems. Up to now, more than 14 subway lines are in operation and some new lines are being built in Shanghai. With the rapid development of the subway rail transit, the settlement of soft clay foundation caused by the cyclic loading ...

The variations on thermal conductivity and structures of silty clay modified by waste fly ash and oil shale ash after freeze–thaw cycles

, 2020
This study was to present changes on the thermal conductivity and structures of silty clay (SC) modified by waste fly ash (FA) and oil shale ash (OSA) after freeze–thaw (F-T) cycles, and discuss the thermal insulation capacity of modified silty clay (MC)

Permeability of Clays, Silty-Clays and Clayey-Silts

2015
ABSTRACT Permeability is the property or capacity of a porous rock, sediment, or soil for transmitting a fluid; it is a measure of the relative ease of fluid flow under unequal pressure (Bates and Jackson, 1980). The most significant characteristic of mudstones, siltstones and shales are their extremely low permeability.

A dynamic strength criterion for frozen sulfate saline silty clay under cyclic loading

, 2020
The strength properties of frozen saline soils under cyclic loading are more complex than those of unfrozen soils and frozen salt-free soils due to the existence of salt crystals in soil matrix.
