METHOD TO DESIGN STRUCTURE PREVENTING COLLAPSE OF ROCK

摘要

FIELD: construction.;SUBSTANCE: invention relates to the field of construction, in particular, to methods to design structures preventing rock collapse onto objects of transport construction, such as highways, for instance, and provides for creation of a strong structure preventing collapse of rocks from slopes. The method includes the following stages: studying and definition of work site data, calculation of a geological model, definition of data of anchor types for reinforcement and intervals between them. Then they calculate the size of the block for stabilisation and inspect the anchor for reinforcement using data produced at the previous stages, when the block size was calculated for stabilisation and data of anchor type for reinforcement was defined, as well as intervals between anchors. If requirements to the anchor for reinforcement are not met, they return to the stage, where anchor type data was determined for reinforcement, as well as intervals between anchors. Then the type of mesh cell is inspected, and if requirements of mesh layout are not met, the cells are put in compliance with requirements of mesh layout strength, and then return to selection and setting of the mesh cell type or reduce intervals between anchors. Then they return to definition of anchor type, interval between anchors and their length.;EFFECT: development of a strong structure, preventing collapse of rock from slopes.;3 cl, 12 dwg
