I am designing (structure) an RCC cast in place storm water drain running along the road. They are going to use a 12tons (6tons static + 6tons centrifugal) compactor for compaction of road layers. I haven't seen any ACI provision which talks about method of inclusion of compactor load. From one of the threads on this forum I came to know about "CANADIAN FOUNDATION ENGINEERING MANUAL" which gives a method to include compactor load for retaining wall design. My questions are:
1. My retaining wall is 6" thick and 2-3 ft high, as per calculations (from Canadian manual) it is safe to withstand lateral pressure due to compactor but is it practically safe? 6inch seems way less for a 12tons compactor. Can this load specially vibration cause my wall to fail or induce any crack etc? Am I missing anything?
2. How do you estimate surcharge load in "load/unite area" due to vehicles acting on retaining walls?
2. Do you include such compactor's load for your wall design?
Thanks in advance
