| Summary: | 碩士 === 國立高雄第一科技大學 === 營建工程所 === 95 === In traditional and ancient Taiwan, using the balance method of dig and embankment to build the hill road owing to the poor conditions of topograohy, and the RC wall structure as the road foundation, breaks the stability of hillside. When the typhoon or heavy rain coming, the poor drainage inducing the collapse of road foundation and damage road to bring some negative effects of permanent usage.
The recovery of the collapsed mountainous roadways usually worked in the condition of limit space of road dike. When choosing the ecological reinforced road dike structure method has the advantage of low environmental impaction and work fast, while due to the insufficient length of material extension causes the reinforced road dike not to maintain the stability. To improve the disadvantage, if add the soil-nail in the back side to strengthen stratum and can increase the road dike stability, and planting in the slope surface according the ecological engineering demand after the work finished.
The reinforced road dike connected soil-nail structure is a complex system work method, and the safety has been confirmed by theory to some extent. By the field static loading and traffic loading test used in the reinforced mountainous roadways dike system, to verify the tensile resistance of the reinforced grid-net and steel rope connected system and the safety of being forced soil-nail. On the safety of stability condition and focus on the repair of the collapsed road dike, and on the impaction of environmental landscape, economic, work-period, and the ease or hard in work, to assess and discuss the possibility of reinforced road dike method to use in the hill-road and offer the reference to the government of the repair of collapsed road dike in the hill area.
