It seems that use of the Robertson charts (Robertson, P.K. [1990] " Soil Classification using the cone penetration test" Canadian Geotechnical Journal 27(1), 141-8) to classify soil type based on CPT results is widely accepted practice in the Netherlands. I cannot, however find any prescriptions...

Hey all, I am studying a geotechnical course in the Netherlands which is heavily based on the NEN-EN 9997 guidelines. These are simply the Dutch amendments to the more general Eurocode 7. In the text for this course they explain that the norms categorize geotechnical constructions into 3...

I am tasked with determining general depth-damage functions for road assets including tunnels, culverts, roads and bridges for the primary road network of a country in the Balkans. I will be receiving flood hazard maps containing flood depth at various return intervals. I also have the...

Hello, I am an engineer working for a consulting firm in Europe. I am assigned the task of coming up with fragility curves for road assets in an Eastern European country. I have very little expertise in fragility curves. Of course we are not asked to develop our own fragility curves, but if...

I would like to derive material parameters based for a simulation which will implement the mohr coulomb and/or hypoplastic material model based on the following information: • Heavily overconsolidated • Very dense, fine sand • In situ preconsolidation pressure of 1 MPa • Bulk unit weight of 20...

I have a small research project related to using large deformation numerical methods in geomechanics. Particularly, I am exploring possibilities of modelling excavation problems using the Material Point Method. Beyond the modelling aspect, I would like to understand how this novel method can...

Hello, Does anyone here use RocScience RS3? I am trying to validate the Modified Cam Clay model using the analytical solution shown in https://www.rocscience.com/help/RS3/webhelp2/pdf_files/verification/Verification_018_(Drained_Triaxial_Compressive_Test_of_Modified_Cam_Clay_Material).pdf In...

I am using Windows 7 64-bit with Intel Parallel Studio XE 2013. I have a .FOR file that contains the following line called within a module: use mkl_dss which obviously comes from the Math Kernel Library. I tried compiling at as shown below: D:\TEMP\TRUNK-IFORT>ifort -free -fpp...

I am a researcher working on modelling soil liquefaction due to induced seismic excitation. The FEM code I am using is Plaxis2D. Plaxis2D can model the onset of liquefaction using advanced constitutive models such as UBC-SAND. I am however interested in doing this for more basic material...

I have a large program containing 40 source files that I am trying to migrate to `gfortran` compiler. 39 of these source files contain module definitions (only) and 1 of these files contains a main program. The main program references 12 of the module definition source files via `use modulename`...

I am trying to compile the sample code provided in example 1 of [this link][1] using GNU Fortran. I have placed the source code in a .f95 file called "Test" and tried to compile it in `cmd` using `gfortran test.95` This throws quite a few errors as shown below: C:\Program Files...

Unfortunately I have not received assistance for this problem so far but I will attempt re-formulating it. Loading: 1 kPa downward (constant) Const. model for soil medium: Mohr-Coulomb Analysis: Dynamic duration: 1 second state variables: Displacement, Velocity and acceleration I have 2...

Unfortunately I have not received assistance for this problem in the geotechnical forum so I am now asking it here. I am responsible for validating an FEM model of the following problem: Loading: 1 kPa downward (constant) Const. model for soil medium: Mohr-Coulomb Analysis: Dynamic duration: 1...

I'm a structural engineer recently converted to the dark side (geotechnical engineering). I understand there are drained, undrained and dry conditions for soil samples. Dry conditions mean no pore water exists and all the voids are filled with air. Drained conditions mean that pore water exists...

This is a geotechnical problem that I am seeking an analytical solution to. A soil layer of depth H and width L is loaded in plane-strain by a periodic load of F=sin t, where F is in units of Force/Length^2. The soil layer is perfectly linear elastic, fixed at the bottom in horizontal and...

This is a basic question but for some reason it has me stumped. I am modeling a continuous load on a soil layer on a commercial FEA package. This is a plane strain problem where the layer is modelled 20m wide by 10m deep. I am trying 2 variations with 0.2 m thickness and 1 m thickness. The load...

Hello, I am modelling vibration of a generator atop a 10m deep layer of soil. I would like to, if possible, eliminate the initial phase from my analysis. My current phases are as follows: Initial Phase (Phase 1) Calculation Type: Gravity Loading[\indent] ΣM_weight: Varies, this is the purpose...

Hello, I am looking for the following document: Bhave, P.R. 1991. Analysis of Flow in Water Distribution Networks. Technomic Publishing. Lancaster, PA. I would order this book from the publisher and pay for it. However I am in a country which in imposing steep tariffs for shipping items from...
