Disposal of drilling waste in construction The methods of disposal of drilling waste are considered and the mechanisms of their biological purification by microorganisms are described. A technology for the disposal of biologically purified drilling mud is proposed by manufacturing concrete structures of marine artificial reefs, barrier breakwaters and other products on an offshore platform. Compositions of fine-grained fiber-concrete mixtures have been developed, including Portland cement, biologically purified well drilling waste, basalt fiber fibers and superplasticizer "SP-3". The sufficiently high parameters of the strength characteristics and frost resistance of the obtained fiber concrete compositions have shown the possibility of their use in harsh climatic conditions. materials.

The article discusses the methodology for deploying dual-purpose military infrastructure facilities, including a model for optimizing the placement of the service network in garrisons, where it has already developed, and the question is its reconstruction and expansion. The calculations are made on the example of service in military camps. To optimize the placement of the service network, a criterion is adopted to minimize the service time.
