Trying to enter rock parameters into Shoring Suite. Entering it as equivalent Clay but not sure if I should give a friction angle and cohesion. The rock is siltstone, compressive strength 1500 ksf, shear strength 2.6 ksf. Is there a rule of thumb that you follow to enter rock and equivalent...
Working on a fairly simple sheet pile design which is nice because it's my first one. It's for DOT and LRFD is required. I'm using Shoring Suite Software. I started out using Strength Case Load Factors for all of the loading. 1.5 for Earth Pressure. 0.75 for Passive Pressure, 1.75 for Live...
We have a bridge project where the bridge pier spans a subway. In order to avoid loading the subway it was proposed that we put caissons on either side of the subway to carry the load from the bridge. The top of the subway is approximately at the top of the rock so the caissons will be...
I'm working on a project using vertical and battered micropiles to support a bridge pier. The lateral load of the pier is designed to be taken by the batter of the piles. In the most recent design runs the worst case ratio is roughly 15 K load vs 70 K resistance factored using the horizontal...
I have a project in which a bridge abutment foundation is proposed on bedrock of very poor quality and is being analyzed as equivalent soil mass. The foundation is also next to a slope. My question is do I need to evaluate the bearing resistance using AASHTO, 2010 Section 10.6.3.1.2c or will...
