A project I am working on has a large slope of Talus that is at about 1.4H:1V in its current natural condition. The slope rises for 400 or 500 feet above the project. Near the top of the slope the granitic beadrock is exposed. The project plans on cutting into the slope at the toe to construct a parking garage and some other buildings.
Cuts may be from 20 to 40 feet vertical, and about 60 to 140 feet hoizontaly into the slope. The talus varies in size from about 3 inches to about 24 inches with a good sandy gravel matrix infill.
I am considering several things for field exploration and would like to know what experiences any of you may have had working in talus slopes.
Has anyone had any luck with geophysics? I would like to find the bedrock profile below the talus, to check the slope stability once we pull out the toe. Has anyone had any luck with using an airtrack to drill into this stuff?
