In order to utilize the Equotip hardness tester, originally developed in the field of metallic engineering, as an indirect method to predict the unconfined compressive strength (UCS) of rock, laboratory tests were undertaken to establish the UCS, Equotip hardness (L-value) and porosity of nine rock types. Using existing data from Verwaal and Mulder (Int J Rock Mech Min Sci Geomech Abstr 30:659–662, 1993) and the results of laboratory tests, an equation relating UCS (MPa) and L-value obtained from single impacts (L s) and porosity (n %) was derived, which provides a close approximation of the UCS value. An equation to relate UCS and Equotip hardness is also presented, although this is less accurate. It is considered Equotip testing has advantages over the commonly used Schmidt hammer test.   相似文献

The heterogeneous Plio-Quaternary coastal aquifer of the Mamora Basin is the most significant reservoir of Morocco. It is composed of sandstones, conglomerates, limestones and more or less argillaceous sands. The increase in the requirements for water in this area requires further information on the relations between the geometry of the aquifer and the salinity of the water. A hydrochemical analysis was undertaken and highlighted three zones of high mineralization. A geophysical approach allowed the determination of the principal aquifer levels, the localization of the various types of water (fresh, brackish and salt) and the geometry of the aquifer base. The results obtained by these two approaches provide a better image of the phenomena governing the groundwater flows and their interactions   相似文献

This paper proposes a multi-region growth model with endogenous labor supply, endogenous amenity, and capital accumulation. Although the production side is the same as in the neoclassical growth theory, in order to solve issues related to regional migration with capital accumulation we propose an alternative approach to consumer decisions about time distribution between work and leisure, housing consumption and saving. We show that the dynamics of the J-region national economy can be described by J-dimensional differential equations. We simulate the long-term economic structure of the national economy with three regions. It is demonstrated that with the Cobb–Douglas production functions and specified values of the parameters, the national dynamics has a unique equilibrium. We also carry out comparative statics analysis with regard to productivity levels, amenity parameters, propensity to save, and the population.  相似文献

There is general belief that the rate of firefighter injury can be lowered by creating fire service cultures where firefighters more closely follow their training and standard operating guidelines (SOGs). That is, there is a desire to minimize cases where firefighters operate outside of the SOGs. Interestingly, there is scant data on the rate of adherence to SOGs in the fire service. In an attempt to better understand the compliance to fireground standard operating guidelines, an analysis of firefighter compliance to Austin Fire Department’s guidelines was performed. We analyze over 1000 survey responses taken from Austin firefighters on fireground operations over a 1.5 year time frame. This paper does not critique the department’s procedures or the officers’ actions, but simply reports the compliance data and discusses some implications of the data. Austin Fire Department (AFD) in the process of creating their current version of standard operating guidelines developed an initial tactical function assignment rule called the “90/10” rule. This rule states that in 90% of situations, personnel are expected to comply with their SOG specified initial tactical functions. Although this rule was proposed several years ago there had not been testing to indicate if the rule was being upheld. By analyzing the initial tactical functions, we first discuss the rate of adherence to the 90/10 rule. We then conducted a more in-depth study to test if other SOG directives (e.g., tactics) are complied to with the same frequency. There were three specific tactics studied – a size-up tactic, a primary firefighter safety tactic, and a fire attack tactic - which had varying ranges of compliance compared to the “90/10” rule. After examining the compliance data, computer simulations were conducted on the fire attack tactic to better understand how a change in the tactic could affect firefighter working conditions.  相似文献
