摘要

在过去的几十年里,数值模拟已被广泛用于模拟岩土工程问题中的岩体行为。数值模拟的唯一缺点是所需输入数据(例如力学参数)的可靠性,由于岩体的复杂性、项目预算、可用的测试方法或人为错误,这些数据并不总是完全提供。另一方面,在许多情况下证明,数值模拟是解决此类复杂问题的有用工具,特别是当与实验室和现场试验结果相结合时。本文在室内试验结果的基础上,尝试确定合适的岩石数值本构模型及其力学参数,以便进一步模拟岩体响应。为此,考虑了现有的本构模型,包括力学参数。通过将数值模拟结果与Bogdanka煤矿岩样单轴抗压强度室内试验结果进行比对,验证了所选本构模型的模拟效果。所有数值模拟均采用有限差分法软件FLAC3D进行

Numerical modelling of Uniaxial Compressive Strength laboratory tests
In the last decades, numerical modelling has been widely used to simulate rock mass behaviour in geo-engineering issues. The only disadvantage of numerical modelling is the reliability of required input data (e.g. mechanical parameters), which is not always fully provided due to the complexity of rock mass, project budget, available test methods or human errors. On the other hand, it was proven in many cases that numerical modelling is a helpful tool for solving such complex problems, especially when coupled with the results of laboratory and in-situ tests. This paper presents an attempt to determine the proper numerical constitutive model of rock and its mechanical parameters for further simulating rock mass response based on the outcomes of laboratory testing. For this purpose, the available constitutive models, including mechanical parameters, were taken into account. The simulation performance with the selected constitutive models is demonstrated by matching the numerical modelling results with the uniaxial compressive strength laboratory tests of rock samples from the Bogdanka coal mine. All numerical simulations were carried out using the finite difference method software FLAC3D
