Abstract
Способ определения параметров моделей грунтов и материалов с помощью измерительно-вычислительного комплекса автоматизированной системы испытаний в строительстве (ИВК АСИС), содержащего прибор (механическое устройство) силового нагружения, применяемый при определении параметров моделей материалов, с набором датчиков, подключенных к аналого-цифровому преобразователю (АЦП) и цифроаналоговый преобразователь (ЦАП), выходы которых через интерфейсы RS-485 и RS-232 соединены с цифровой электронно-вычислительной машиной, имеющей программные средства обработки результатов (данных) измерений и управления силовым нагруженном, отличающийся тем, что по данному способу производят одновременные физические испытания образцов одного и того же материала, используя произвольное число приборов силового нагружения, проводят испытания при различном виде напряженного состояния и траекториях напряжений, определяют начальные значения параметров для выбранных моделей материалов, выполняют численное моделирование испытаний, результаты численного моделирования идентифицируют с результатами механических испытаний с использованием различных моделей материалов и одного из методов оптимизации, выбирают модель материала, наилучшим образом отвечающую результатам механических испытаний. A method for determining the parameters of soil and material models using the measuring and computing complex of an automated test system in construction (ICS ASIS) containing a device (mechanical device) of power loading used to determine the parameters of material models with a set of sensors connected to an analog-to-digital converter ( ADC) and digital-to-analog converter (DAC), the outputs of which are connected via RS-485 and RS-232 interfaces to a digital electronic computer with software environments to process the results (data) of measurements and control the power loaded, characterized in that this method performs simultaneous physical testing of samples of the same material using an arbitrary number of power loading devices, conduct tests with different types of stress state and stress trajectories, determine the initial parameter values for the selected material models, perform numerical simulation of tests, the results of numerical modeling are identified with the results and mechanical tests using various material models and one of the optimization methods, choose the material model that best suits the results of mechanical tests.
