Generate a 3D dam model from 2D cross-sections AutoCAD/Civil 3D

Hello,
I need to develop a 3D dam model from 2D cross-sections AutoCAD/Civil 3D. The dam spans 900 kms. I have 2D cross sections for every 30m intervals. There are geotechnical zones. I have attached some files of cross sections and the dam axis where all sections will be aligned. All 2d sections will be aligned with respect to their leftmost crest. How do I interpolate the consecutive sections? Once interpolated I need to group them.
I can use LOFT for sections that are evenly spaced but that does not help if my dam axis curves (I have 2 curves). I can work with AutoLISP scripts for task automations. I need to develop a 3D model for a 3D geotechnical analysis.
Any kind of help is much appreciated. I have been stuck in this pickle for quite a while and scoured through a lot of material but no luck soScreenshot 2025-01-20 095047.pngScreenshot 2025-01-20 100820.pngScreenshot 2025-01-20 100920.png far.

@hosneyalaa My final 3D model should look like this. I used LOFT command to connect each 2D cross section. This model is not correct. The layers need to be connected with each other. There are gaps. I need to make accurate model to import it in 3D geotechnical analysis software later.
