6 FAQs about [Performance parameter comparison of Chinese surface rock]
Can hard rock TBM performance be predicted in China?
In order to develop an empirical model for hard rock TBM performance prediction with more suitable applicability in China, 49 valid datasets were collected from a water conveyance tunnel mostly excavated in medium to hard igneous rocks, and the empirical relationships between TBM performance and each parameter in the database were studied.
Do rock mass classification systems affect TBM performance?
As stated by Hamidi et al. (2011): “these existing rock mass classification systems with limited accuracy in TBM performance prediction were designed with special weighting system for each rating factor for use in ground support design and not mindful of their influence on TBM performance”.
How do 'average' and'mean' properties affect rock engineering design?
When applying this procedure to rock engineering design problems, most users consider only the ‘average’ or mean properties. In fact, all of these properties exhibit a distribution about the mean, even under the most ideal conditions, and these distributions can have a significant impact upon the design calculations.
How to calculate uniaxial compressive strength of saturated rock?
Then uniaxial compressive strength of the intact saturated rock can be calculated using Eq. (4) (The National Standards Compilation Group of People’s Republic of China, 2014): (4) R c = 22.82 ∗ I s (50) 0.75 where Is (50) is the corrected point load strength index of rock sample with 50 mm diameter (MPa).
Why are rock mass classification systems not suitable for evaluating rock mass boreability?
This is mainly because that, On the one hand, the influence parameters of rock mass boreability are somewhat different from the ones controlling the stability of surrounding rock; on the other hand, the ratings assigned to the input parameters of these rock mass classification systems are not suitable for evaluating rock mass boreability.
What criterion is used to study progressive failure of rock masses?
When using numerical models to study the progressive failure of rock masses, estimates of the post-peak or post-failure characteristics of the rock mass are required. In some of these models, the Hoek-Brown failure criterion is treated as a yield criterion and the analysis is carried out using plasticity theory.
