Title

Reliability Analysis of Bearing Capacity of Foundations on Rock Masses Using Monte Carlo Method

Pages

  11-23

Abstract

 Summary One of the possible choices for the foundation of large scale structures like dams and bridges is to build it on rock masses. In comparison with soils, most rocks have more strength-and that means more Bearing Capacity. So, the load of structures on rock mass usually causes no problem from bearing point of view. One of the terms of safe application of foundations is to bear the load structures or in the other hand Bearing Capacity of foundation is adequate for load structures. Estimating Bearing Capacity of foundations has been one of the most important problems for geotechnical engineers and because of its importance; several relations have been suggested with different researches. A typical method in design of structures in geotechnical engineering is safety factor that is a stuffy method and even in most cases lead to increase in project costs. However, not paying attention to the Reliability of soil or rock parameters, even in a small scale, and using just a number as safety factor is not logical. Reliability and error is a common problem in geotechnical engineering and especially in Rock Mechanics. So, using Reliability methods in geotechnical engineering has been common. In these methods, by using a range of probable values for parameters, variation of the function will be determined. Since using probability methods especially in geotechnical engineering is so limited, in this study, the most common method for Reliability analysis “ Monte Carlo” was introduced and Reliability relations for Bearing Capacity of footing on rock masses was proposed. Using the proposed method in this research, Bearing Capacity of a strip footing on rock mass located in Ankara (Turkey) was studied and finally, the accuracy of results from different probabilistic methods is compared with results of deterministic method. The modified Hoek-Brown failure criterion was used to study the Bearing Capacity. Finally, a probability distribution of the Bearing Capacity was estimated and the probability of failure was calculated.
