✦ Synopsis

An equivalent continuum model of rock mass consisting of joints and rock is proposed by averaging the stress and strain in a volume element. Using the theory of damage mechanics and fracture mechanics, the damage tensor, effective stress tensor, damage strain, etc. of the rock mass are defined, propagation of damage is developed and a constitutive model of a jointed rock mass is established. The constitutive model is used for the numerical analysis of an engineering case.

This work presents a finite element implementation to treat the Hydromechanical Coupling (HM) in fractured rock masses under the framework of the so-called 'equivalent continuum' approach. The multilaminar concept, introduced by Zienkiewicz and Pande, is used to simulate the mechanical behaviour of

Electrospray mass spectrometry (ES-MS) has been applied to a variety of zinc O,O'-dialkyldithiophosphate (DTP) derivatives. The neutral Zn(DTP)s compounds were converted to the [Zn@I'P)s]-anions by reaction with excess DTP-and these principal anions are readily observed by ES-MS. Exchange reactions
