수치해석과 모형실험을 통한 Fiber Mat의 Sand Mat 대체 가능성 연구 = A Study on the Substitutability of Fiber Mat for Sand Mat

다국어 초록 (Multilingual Abstract)

At present, there are several problems related with sand mat which has been used as a way to accelerate consolidation settlement. First of all, the unbalance of the demand and supply of sand is the one of the biggest problems. Secondly, the damage of ecosystem and scenery is triggered by thoughtless sand dredging or mining. So, the need that the sand for sand mat should be replaced with a new environmental friendly material has been increased.
Fiber mat may be one of the proper materials that suits the need. Therefore, we intended to compare the drainage properties of sand mat with those of fiber mat by experimental model tests and 3D finite element method. On the basis of the test results, fiber mat took a little bit shorter time of consolidation than sand mat and it's amount of settlement showed a little bit bigger than the other. Results of FEM program are also shows that Sand Mat can be substituted by Fiber Mat.
