The analysis of landslide slope stability since 1960s is the development a 2-D structure proposed by various experts, through 3-D method. Most these previous studies stated that ratio and safety factors was more than one for cohesive less non-cohesive soils. These were because several required reinforcements affected factors, with analytical differences methods causing distinction in requiremen...

PT. Berau Coal is one of the mining companies in Indonesia that focuses on coal and sales. This research was carried out haul road at Site Gurimbang Mine Operation, where condition currently undulating located above a swamp area. reduces speed HD 785, resulting unit's productivity not achieving company's target.

BACKGROUND: In the early 1990s, some U.S. Army Corps of Engineers Districts began using and evaluating custom-made geotextile tubes with fabric tensile strengths ranging between 400 and 1,000 lb/in. (70,000-175,000 N/m). The tubes have been used as containment dikes for dredged material placed in shallow water to intertidal elevations. Wetlands have been restored on the dredged material with th...

Splitting spunlaid composite filament is a most significant technique to manufacture nonwoven with microfibers. The splitting effect of composite filament is a direct impact on the performance of the final products. The paper summarizes present methods of splitting composite fibers at home or abroad, and the principle and characteristic of each method is also described in order to discuss the m...
