Las Colinas 2001 Landslide – Study on Mitigation through Slope Reinforcement
Racquel Nottingham and Freddy Lopez
Landslides have been and will be a perpetual and reoccurring hazard worldwide. The extent of damage can range from minor losses in forested areas to complete death and devastation in cities. South and Central American countries are particularly vulnerable to landslides. In 2001 a strong earthquake hit the region and devastated El Salvador, particularly the Santa Tecla region where thousands of people died. Mitigation is the key to success for landslides and it has been made possible in different ways. This paper discusses the failure and proposes a solution using Ischebeck Titan self-drilling soil nails with a high-strength reinforcing mesh on the slope surface.

Fischer heavy-duty fixings secure Świna Tunnel on Poland’s Baltic Coast
Poland’s longest underwater tunnel thus far, the Świna Tunnel, is currently being built between the islands of Uznam and Wolin in the city of Świnoujście. The tunnel below the river Świna will connect the coastal region more closely to the rest of the country and the world. More than 50,000 heavy-duty fixings by fischer have been used to reinforce the tunnel.

Increasing the Resilience of Underground Public Transportation Systems
Christian Thienert, Christophe Willmann, Christophe Chaize and Annie Pauzie
This paper presents some interesting results from the research project “U-THREAT”, which has intensively dealt with the question of how to further increase the resilience of underground public transportation systems in crises. It includes a corresponding evaluation within the framework of a large-scale exercise in the Lyon metro (France) combining a fire fighting and an evacuation exercise and the communication between different institutions and actors.

Possible Effects of Dust and harmful Gases on Underground Fans
Ventilating fans intended for use below ground have to be deemed ‘fit for purpose’ and they must be designed in a way that takes account of the proposed operating conditions. Practical experience with fan systems has pointed to the negative impact created by dust and gases, a factor that is often overlooked at the equipment planning and assessment stage.
