Considerations For Judging Suitability of Filling Materials For an SCP

For the implementation of substitute filling materials for an SCP, their evaluation needs to be made in advance by means of simple soil tests. Field site tests using such materials have been conducted so far by examining their suitability for ease of implementation and improvement effect. These procedures were timeand cost-consuming, however. This paper proposes a design flow to assess the applicability of filling materials to an SCP, based on the findings from available laboratory and field site test data. Further, the suitability of the proposed design flow is confirmed from the results gained by applying it in tests and actual implementations.
