Foundation Stability Check Report

This document provides design calculations for the foundation of a new asphalt production building. It calculates the various loads that will bear on the foundation, including the weight of the building structure, equipment, and potential blast loads. It then checks that the foundation will be stable against sliding and overturning. The calculations show that the total resisting friction force is 1.2 times the maximum sliding force, and the total resisting moment is 5.7 times the maximum overturning moment, meeting the safety factor requirements.
