      Abstract: To improve the anti-penetration performance of conical prestressed concrete and obtain the prestressed size of the target quickly, it is necessary to study the prestressed size and distribution law of the concrete target. Utilizing a numerical model verified by the test results, this study examined the distribution law of circumferential, radial and vertical prestress of the target. Furthermore, a mechanical model based on the prestressing constraint method of the cone-table was developed, and the fast prediction formula was derived and verified by the test, offering a reference for the experimental research and the optimal design of prestressing in engineering applications.
