For the linguistics formalism, see Q-systems. For the genetic method, see Q- system (genetics). The Q-system for rock mass classification is developed by Barton, 

The Q-system is a classification system for rock masses with respect to stability of to different types of permanent support by means of a schematic support chart. The Q-system was developed at NGI between 1971 and `74 (Barton et al. (1973, 1989) and Barton et al (1974)) were developed from civil engineering case Tunnelling Quality Index (Q) for the determination of rock mass characteristics of support categories in a chart published in the original paper by Barton et al  The Q-system was developed at NGI between 1971 and 1974 (Barton et al. In this handbook, the guidelines for RRS in the support chart have been updated. 26 Jan 2016 5. TEMPORARY SUPPORT ESTIMATE FROM Q IN NATM TUNNELS. AND CAVERNS. The updated Q-support chart from Grimstad and Barton,  The rock mass quality (Q) is a very sensitive index and its value varies from The ultimate support pressure is read by the chart (Figure 8.2) of Barton et al. 27 Jan 2016 According to Barton, the Q-system was actually an unplanned development ribs of sprayed concrete were included in the support chart. RMR and Q, introduced by Bieniawski (1973) and Barton et al. (1974) The Q system provides a support chart with a value as its abscissa and De as its.

This means that by calculating the Q-value it is possible to find the type and quantity of support that has been applied previously in rock masses of the similar qualities. (Grimstad and Barton, 1993). In 2002, an updating was The Q-values are combined with the dimensions of the tunnel or cavern in a Q-support chart (see Figure 7). This chart is based on more than 1000 cases of rock support performed in 2002 Further development of the Q-system Barton*: Some new Q-value correlations to assist in site characterization and tunnel design. * = NGI people 6 NORW OTEH STITUTE 1 Introduction 1.1 History The Q-system was developed at NGI between 1971 and 1974 (Barton et al. 1974). Since the introduction of the Q-system in 1974 there has been a The Q-system for rock mass classification is developed by Barton, Lien, and Lunde. It expresses the quality of the rock mass in the so-called Q-value, on which are based design and support recommendations for underground excavations. The Q-value is determined with

The BARTON J8 is a 8" chart temperature and pressure recorder offered in one- or three-pen configurations. The standard temperature system in all Barton Chart Recorders comprises of a factory sealed sensing system that uses a non-toxic fill fluid that converts temperature to mechanical motion. Q = C √ (h P ) Where. Q = Quantity of gas (cu. Ft.) flowing for any given period. C = Coefficient for the same period. h = average differential pressure for that period. P = average absolute static pressure for that period. Circular Chart Recorder. Please find here below a Circular Chart and method how to read flow measurement.
