Thanks Dr. Naveen

The software you suggested seems to be a tunnel project management or construction oriented software. But I need a tunnel design only software. Could you suggest another software more specific to tunnel design, please?

Thanks  a lot for your help.

If you need to study the tunnel soil interaction problem then PLAXIS3D - TUNNEL software is well suited to your problem. You could find lots of literature related to the simulation of tunnel using PLAXIS3D software.

Thank you Mr. Karthigeyan.I explores the Flaxis3D on google and it is really very good software but seems to be costly.!

FLAC by ITASCA is an excellent software. I have personally used it. You may go for 2D or 3D options based on your budget.

Thanks Mahiva. Could you tell me the approximate price of FLAC3D, please?

Hi Mr. Ullah!

It's depends on your purpose and how mush you want investigate. But, generally I suggest you:

1. FLAC2D and FLAC3D (Itasca) is a completed software with most purpose of civil engineering problems.

2. PLAXIS3D (not PLAXIS3D Tunnel) made in Netherland; in this version of software you can model a tunnel in the 3D space and there are many soil behavior in this version. I don't suggest the PLAXIS3D Tunnel software, because it is not completed model and you can special case such as tunnels junction, niche, cross section of tunnel and shaft, and etc.

3. GTS-NX Midas (made in Korea) is the best software for you goal. It has a lot of soil behaviors, you can import the CAD3D file to the software, it is almost user-friendly, and etc.

4. UDEC and 3DEC (Itasca); if you just simulate the tunnels in the discontinues media.

I hope that this answer can help you.

Thank you Mr. Basirat.

Now I have a lot of information about tunnel software which could be summarized as follows:

1  FLAC2D and FLAC3D (Itasca), USA

2. UDEC and 3DEC, (Itasca), USA

3. PLAXIS3D, Netherland

4. GTS-NX Midas, South Korea

5. C-Tunnel (Itech+CETU), France

Could anyone give the corresponding prices of the software as well?

As per my experience among these software PLAXIS3D software is costlier as compared to all other softwares.  

Thanks a lot Mr. Karthigeyan. Is the C-Tunnel free of cost?

RS2 (from Rocscience, canada) is mostly used and user friendly. It was called Phase2 in the past.

Wawo. What a great reply. I had already heard of Phase 2 but I did not know that its latest version id RS2. Do you know its expected price? What are the main features of RS2? Is it suitable for Asian region as well?

Dear Mr Shafi Ullah,

I recently bought it for USD 5000 and for single user. I think it costs more if multi user version needed. I used FLAC in the past. Nowadays I enjoy using it mostly for rock tunnel stability analysis in Himalayan tunnel. please visit rocscience website - for its features.

As a point of my view, Plaxis 2D might be an excellent software for Tunnel.

Good Luck

Thank Mr. Arpit
