Taiwan has a mountainous island environment and as industrialization has replaced agrarian development, changes in life styles and dietary habits have resulted in the gradual decline of agriculture. This has made it more difficult to make a living in rural areas and further encouraged people to move to cities. As a result, rural counties and cities are experiencing rapid ageing and the loss of much of their population. At the same time, because urban areas have more resources they also attract students and those looking for work. However, the availability of land to build suitable housing for all these people is becoming increasingly scarce, forcing future development to focus on urban renewal and suburban development. If we take Taipei City and New Taipei City as an example, both have suburban areas than can still be developed, but these are adjacent to hilly areas. The future development of such areas requires reinforced soil retaining techniques that differ from the diaphragm walls (Diaphragm wall) most often employed in urban areas, requiring the use of Prepakt mortar piles, steel sheet piles (prepare-in-place piles, steel sheet piles) etc. As such, it will become increasingly necessary to use one or more reinforced soil retaining techniques on construction sites.
In order to emphasize the rationality and practicality of this research model, we focus on the deployment of reinforced soil retaining construction machines and tools. On-site techniques include Prepakt mortar piles, steel sheet piles (prepare-in-place pile, steel sheet piles) used in conjunction with simulation testing in an effort to achieve optimization and minimize costs, comparing this to the cost of real world labor allocations to confirm lower costs and greater efficiency. This can also be used as a timely reference to enable those in charge to make more accurate decisions. This research can also be applied to the assignment of machines and tools on construction projects.
Key Words: prepare-in-place piles, steel sheet piles, integer programming, optimization
