Harald Golser,Wulf Schubertonomic aspects.Among scholars as well as practitioners it is taken for granted that liability insurance and liability in tort interrelate in many ways. In fact, insurance carriers are major players in the area of claims for damages. In striking contrast to common beliefs among lawyers, the law still

Introduction,els through the Alps in order to allow the environmentally friendly transport of goods from the northern to the southern part of Europe involve high overburdens and difficult ground conditions. The planned . will involve underground space for the transport of people and goods as well as for housing.

Tunnelling - the need for technological development and innovation,r excavation and support were adopted also for the traffic tunnels. In contrast to tunnelling, in mining only a rather small portion of the underground structures is designed for permanent use. The rock mass conditions in mines are usually well known due to the long experience gained during the life

Improved site investigation Acquisition of geotechnical rock mass parameters based on 3D computer vr decision making processes during all phases of projects, ranging from feasibility studies to construction and maintenance. The present system of data acquisition, specifically applied during underground construction works, has a number of constraints. Sampling bias may be caused by the “human fact

Thermochemomechanical material model for shotcrete, thermochemoplasticity is presented. It accounts for hydration kinetics, chemomechanical couplings related to strength growth, stiffness properties, and to autogeneous shrinkage in early-age shotcrete. Creep is modeled by means of two mechanisms: stress-induced water movement in the capillary pores

Material model for soil and applications,el is formulated in the framework of multi-surface viscoplasticity, involving a Mohr-Coulomb criterion for the simulation of compressive loading and a tension-cut-off for capturing the response of soil under tensile loading. Whereas the tension-cut-off is assumed to be ideally-plastic, friction hard
