determing preconsolidation pressure - alternate method
determing preconsolidation pressure - alternate method
(OP)
I remember their being "another" method to determine the preconsolidaton pressure, other than Casagrande's emprical construction method. Either this method is commonly used in Brazil or the person who developed the method is Brazillian. ANyways, this method doesn't rely on picking the point of maximum curvature by eye, its more mathematically based. I think the method is called the Pashako Silva(??) method.
Just wondering if anybody can describe the methodology or give a reference to a paper where it can be found.
Thanks

A second method of determining the pre-consolidation pressure that comes to mind involves the use of the electric cone (CPT) and Schmertman's method. Basically this method looks at the Su/effective overburden stress of the soil and compares it a similar ratio for a normally consolidated soil.
Doing a internet search on Schmertmann and/or CPT on the net should get you started. In addition, I know Matt Kokan wrote a in depth article for the Vancouver Geotech society a few years ago on this subject.
Best of luck

El método que más se usa para esto es el de Casagrande, pero además de este debo utilizar los siguientes:
Métodos de determinacón directa:- Jambu
- Tavenas
Métodos de determinación gráfica: -Schmermann
-Butterfield
-Old
-Van Zelst
Solicito respetuosamente quien pueda proporcionar información o apuntes sobre como se utilizan cada uno de estos métodos y como se grafican para poder determinar la presión de preconsolidación.
