%PDF-1.5 %���� It must be below the frost line. Good construction will keep that job site firmly in place. Reaction blocks are anchored to slopes or existing retaining walls to stabilize them. Maintenance was required to grade the roadway to keep it safe for travel. Even areas of Texas experience frost in the winter. Well established, used elsewhere, adapted locally, Established local practices and materials, Established process elsewhere, adapted locally, New process, conventional materials, demonstrated and proven, Does not require any special safety consideration, Requires some safety precautions and measure, Requires special safety procedure/measure with monitoring. These include retaining walls, soil nailing, ground anchor walls, and the use of horizontal drains. Landslide is a movement of mass of rocks, earth or debris down a slope They are a mass wasting denoting down slope movement of soil and rock under the impact of gravity. The land slide risk mitigation measures may often extend beyond the building area, and property lines, difficult to include within the scope of the building project. Landslide Technology (LT) assisted Clark County with the stabilization of two active segments of the slide, which were termed the “Hillis Hill” and “Hillis Hill No. It traveled 14 miles down the North Fork Toutle River and reached depths as high as 600 feet. Figure 3: Thredbo Landslide (30 July, 1997), Figure 4:Reconstruction of Alpine Way Thredbo, Source: “Landslide disaster prevention and mitigation through works in Hong Kong”, By K.Y Choi and Raymond W.M Cheung (Journal of Rock Mechanics and Geotechnical Engineering). There are several construction methods to mitigate the risk of landslides. 2004. The ranking (Ri) is therefore done on the basis of the summation of weighted (wi) contributing factors (Fi) for each evaluation criterion: Where i = mitigation measures selected by the user for analysis, 1, 2, …, n, w = weighted factor the default value for all wi at start is 1,0. Following phases of investigation, monitoring, and design, the original slide was mitigated with a horizontal drain system installed in October 2001, and has remained stable since then. The decision support matrix can be prepared based on the scoring of factors (Fi) for each mitigation measure the user has to consider, adopt or modify during his/her assessment of the problem at hand. The drainage system is installed and a reinforced shotcrete wall facing is applied. Super Use Case: St Lucia Flood modelling, section 8.4 “Design of structural mitigation measures to protect critical infrastructure in dangerous locations”, http://www.landslidetechnology.com/rockfall.htm, Structural measures could be the measures to strengthen the building/construction itself or any physical construction to reduce the landslide hazard and avoid possible impacts of hazard around the building site.
