“Knock, and the door shall be opened for you.”

Written by Gouw Tjie Liong. Posted in General, Life

Let’s get ready to knock on the 2015 door…

May the door be wide open,

the roads ahead be smooth,

… for us to walk through.

Let’s pray that God guide us through whenever the road of 2015 becomes rough, wavy, and undulating…

Let’s us keeps the high spirits to keep learning …

Learn in every moment of our lives …

Learn to be grateful for every breath we have …

With all the moments we have, sad or happy, let us say goodbye for 2014… and with head upright, hands wide open, we step into 2015…

Keeps the spirits high …

Nurture positive attitude …

Keep and promote green nature..

Not forgetting to keep on learning …

Learn in every moment of our lives …

Learn to be grateful for every breath we have …

Last but not least, thank for being my friends…

Without friends the world will be meaningless…

Happy 2015 for every one of us!!!

AN INVESTIGATION ON THE SUITABILE CONSTITUTIVE LAW FOR MODELLING JAKARTA RED CLAY

Written by Gouw Tjie Liong. Posted in Geotechnic, Technical Paper & Presentation (Others)

Abstract:Having the origin from the sedimentation of volcanic materials, many experienced Indonesian geotechnical engineers have long suspected that Jakarta reddish and grayish clay may have different characteristics compared to other clayey soils known in many geotechnical text books. Despite of carefully derived design parameters, experiences in the execution of deep excavation, be it open cut slope or protected excavation by either contiguous bored pile or diaphragm walls, often show that the performance of the geotechnical structures were better than predicted by the available design geotechnical software. Although, some engineers have started using more advanced constitutive soil models, such as: Hyperbolic and Cam Clay models. Undoubtedly, many engineers still use the bilinear Mohr-Coulomb model in their analysis. So far, to the author knowledge, there is no published paper discussing about the suitability of the soil models for modelling Jakarta red clay, in particular. Therefore, the author tried to find out which soil constitutive models can better predict the behavior of the Jakarta reddish/grayish clay. Available models in PLAXIS software, e.g.; Mohr-Coulomb, Hardening (hyperbolic), and Soft Soil models, were tried by simulating isotropically consolidated undrained triaxial test and compared it with the actual test data. At this stage it was found that none of the model can correctly predict the stress strain curve neither the correct stress path.

Keywords: Volcanic Origin Clay, Jakarta Clay, Mohr Coulomb Model, Hardening Soil Model, Soft Soil Model, Plaxis
