I am looking for any case histories of a quarry-type blast pushing un-shot rock around it by gliding on a bedding plane. I'm not talking small stuff. The incident I'm working on is a block over 100 ft on a side over ten feet thick moving several feet.
Does anyone know of a study relating auto speed/weight to being stopped by or rolling under a vertically falling object of various weights and velocities and geometries? In other words, when a car is hit by a vertically falling object, at what point does a car get stopped dead in its tracks...
I am working on a forensic investigation of a caisson drilling rig that tipped over. I have searched OSHA and google extensively, and can find no similar incidents. Manufacturers supply graphs and charts of limits, but there is always operator error. Any tipping-over incidents would be welcome.
I am looking for a way to predict the generated vibration levels in ips from dynamic compaction by weight dropping at various weights, heights, base materials, and distances.
