Topicality of the article, the goal and tasks of research and design of monolithic reinforced concrete plate of the bottom of the silo using modern software PC«Monomah», taking into consideration the properties of the surrounding soil are justified. Practical application and use of materials of article are given. In the first part of «Research methodology». The source data, methodology of research of the bottom, settlement scheme and application materials of subprogramme PC «Monomah Ground» for the formation of a spatial model of the soil foundation are shown. The main possibilities of the program complex PC «Monomah» and presentation of the obtained results (isofield movements and major plots of stress, reinforcement of plate) are explained. In the second part of the «Engineering-geological characteristics of the construction site». Characteristics of the physical-mechanical properties of surrounding soils are given. In the third part of «Definition of stress and effort in the plate of the bottom of the silo farm.» Design standards in accordance with which the calculations are performed. Determination of the pressure of mass of silo and compacting mechanisms at the bottom is given. In the fourth part «Data input to PC «Monomah». The algorithm of data input in the PC «Monomah», with an explanation of the basic assumptions and references is given. Stages of calculations are given. In the fifth part «Entering the soil conditions in the program «SOIL». Characteristics of soils, introduced in PC «Monomah» are given. In sixth part «Entering wells into PC «Monomah» and modeling of soil». The position of the wells are indicated and on the basis of the geological section, graphic model of soil is developed. In the seventh part «Matching structures to soil models». Matching structures in the regime of import and confluence with the soil model in subprogram PC «Monomah Soil» is explained. In the eighth part «Entering a load on the plate of the bottom». Load and questions of confluence of soil model with structure executed in “Layout" are specified, which allows to obtain the most accurate results in the work of bottom. In the ninth part «Calculation results in PC «Monomah». The results of calculation of the bottom in the form of graphic isofields are given: movements of the bottom, lower and upper reinforcement, bending moments and optimum thickness of a plate. In the tenth part «Entering a reinforcement of the base plate». On the basis of calculation of loads acting on the bottom and soil conditions, the reinforcement of the bottom of the steel reinforcement is given. Conclusion of the research and calculation of reinforced concrete bottom of silo farm are given.

Железобетонное днище силосохранилища должно быть долговечным, прочным и герметичным, эффективно защищать окружающую среду от силосного сока и проникновения грунтовых вод в силосохранилище. Решение этой задачи сегодня актуально. Днище силосохранилища проектируют в виде монолитной железобетонной фундаментной плиты на естественном упругом основании. В статье предложена методика проектирования и расчета монолитной железобетонной плиты днища силосохранилища с использованием современного программного комплекса «Мономах».
