Hi guys. My question relates specifically to scour in bridges over water bodies. I'm wondering what are the essential information that bridge engineers require from geotechnical engineers apart from particle size distribution and atterberg limits testing.
Input much appreciated!
Q1: What is the construction sequence for the batters?
Q2: Hydroseeding with jute matting where the slope overlay is thin. But this technology will not work near the toe of the slope due to thickness. Is the slope stable under its own weight?
I'm using Rocscience's Settle3 to analyse consolidation settlement. Amazing! I can compute immediate and primary settlement so quickly. However, I cannot find the secondary compression part including time step. Anyone know how to work this?
Hi. I am a geotechnical engineer. I received the following sketches from the structural engineer for 2 options of highway gantries. I am estimating pile lengths, without estimated loads from the structural engineer. Can anyone give me a rough idea of how heavy these gantries would be? Rough...
My project involves adding new loading to existing pad footings sitting on 5m fill underlain by soft soils.
I am trying to back-calculate ground compressibility parameters (compression ratio, coefficient of consolidation, permeability and pre-consolidation pressure) from 20+ years of field...
The general bearing capacity equation requires a check of the foundation's rigidity index (Ir) against critical rigidity (Irc). Shear modulus (G) value is required to determine Ir. Is it the small-strain or large-strain shear modulus that should be used?
There seems to be limited literature on running an engineering consultancy that touches on topics such as tendering strategy, professional fees and construction supervision. I only know the following:

With respect to quality control testing of Hot Mix Asphalt (HMA), what is the difference between the Maximum Theoretical Specific Gravity (Gmm) as defined in AASHTO T209, and Maximum Theoretical Relative Density (ST) as defined in BS 598 Part 104 (Appendix E).
I understand that they are...
