Objective: To obtain analytic dependences for profile cubage volume calculation of subgrades (side hill fills), ditch cuts (side hill cuts), as well as borrow pits, soil banks, drainage ditches and other structures. Methods: Integral calculus and stereometry was applied. Results: New analytic dependencies for profile cubage volume calculation of subgrades (side hill fills), ditch cuts (side hill cuts), borrow pits, soil banks and drainage ditches were deducted. Relative errors of calculating the given profile cubage volume were determined in comparison with conventional methods for calculating the values in question. Mathematical demonstration of the given analytic dependencies, as well as the analysis of the latter was carried out. Practical importance: Computational accuracy of profile cubage volume of subgrades (side hill fills), ditch cuts (side hill cuts), borrow pits, soil banks and drainage ditches may be improved based on the examined dependencies. Research results may be applied in the design of information systems. The latter promptly implement the introduced analytic dependencies of more effective calculation indices and test planning of large earthwork volumes.
