The objective of this live only course is to provide knowledge concerning with the usage of the Finite Element (FE) software code PLAXIS for Engineering Rock Mechanics (ERM)-related problems such as underground openings and slopes where the fundamental object of the design process is aimed at enabling a safe and economic design of each part of these structures. An integral part of this process involves the stability analyses of the structure under study along with the effective design of all mitigation works aimed at achieving acceptable levels of risk in terms of safety and economics.
Based on the anticipated failure mode, the scale of the problem, available data and level of the project there are different type of design analysis (e.g., analytical and semi-analytical methods, empirical approaches, numerical methods). However, in order to address geotechnical issues, traditional methods are not suitable because they make many assumptions and therefore oversimplify reality. Numerical methods, which can represent the rock masses based on continuum, discontinuum and hybrid continuum/discontinuum approaches, have thus become increasingly adopted tool to analyze the rock mass behavior and for carrying out the concerning design analyses.
Although rapidly evolving discontinuum and hybrid approaches provide valuable modeling techniques for some applications, continuum methods are still more commonly used in practical rock engineering given the existing experience base in the technical community with respect to modeling rock masses as continua, their relative accessibility and ease of use, and the continue developments and improvements of constitutive models for use in continuum models.
Within the framework of continuum modelling, the FE software code PLAXIS is an efficient advanced modelling tool capable to address the crucial aspects concerning with modelling rock engineering problems through a proper definition of the rock mass model to be used for the numerical analyses, accurate behavioral models from which the analysis can highly benefit along with specific tools for efficiently help the building of the model, especially in those conditions where complex geometries are required for the simulation of equally complex construction stages which also includes the installation of support and reinforcement systems.
The aim of this course is to provide a comprehensive understanding to the use of PLAXIS when dealing with numerical analysis for engineering rock mechanics design. The course intends to cover topics on the role of the rock mass model for numerical analysis, the standard rock mass behavioral laws, the tools aimed at performing effective modelling for the design of various structures in/on rock like tunnels and other underground openings and rock slopes.
The course is divided into three session. The first session will provide fundamentals of finite element numerical analysis for rock engineering whilst the second and third sessions will deal with the simulation of rock engineering works, as detailed below.
In this first session we will introduce how we can apply numerical methods as Finite Elements in PLAXIS to Engineering Rock Mechanics. In this starting session we will cover:
After the first session, we now want to look more in depth into underground structures modeling and how to simulate the construction sequence. In this second session we will discover:
The final session of this course will deal ERM works and mechanisms that happen near surface: excavations and slopes. We will cover:
