Linear and Nonlinear Numercial Analysis of Foundations

Dear all,

Attached is a very interesting file on which you can find several recommandations for building up foundation numerical models. The book treats several types of earth structures as piles, retaining walls, shallow footings, anchored systems, etc…

I hope that it will be useful for all of you.

Good week starting !

Practical Tool for Determining Compressibility Parameters of Clayey Soils

Good evening,

Attached is a very interesting Excel file allowing you to determine compressibility parameters of a given clayey soil based on oedometer data. Further, you can even use such a tool to carry on back analysis based on in situ test results and then run with precision you consolidation analysis.

Hope that it will be useful for you.

Greetings,

Modelling Soil Structure Interaction for Shallow Foundations

Dear all,

Attached are several files pertained to frequently used procedures for modelling soil structure interaction in case of isolated footings, slabs and other types of shallow foundations. I hope that it will be useful for you.

Sincerely,

Sheeting Piles Check and Design

Dear all,

First of all, I apologize for not publishing something since 2 weeks as I was actually busy. In the same context, I would like to thank all visitors of the blog and tell them “It’s just the begining and I hope that this platform will be more dynamic and strongly enrich you in the future”.

Here, you can find 3 interesting documents about sheeting piles (called in french “Palplanches”) check and design. In brief, these files detail the most important methods used by geotechnical engineers to guarentee a consistent and complete sheet retaining solution.

I hope that it will be useful for all of you.

Pile Bearing Capacity using Pressuremeter Test

pressuremeter-test-procedure

Good evening,

Attached are two papers detailing the way to estimate the bearing capacity of a single pile using a Ménard Test (Pressiomètre). Although I’m not fun of the pressuremeter, I’m posting these files as the majority of north african engineers evaluate the bearing capacity according to its results. Based on the little experience that I have as a geotechnical engineer, the correlations proposed by Ménard  to estimate the deformation modulus of a soil layer underestimate the soil stiffness. Soon, I will post a detailed work confirming this point of view. Your critics and comments are welcome.
