以地盤改良工法做為野溪固床整治方法的評估研究

In response to the government's circular economy and net-zero carbon emission policies, the dredged soil and rocks in stream were improved on-site into materials for protection and renovation methods such as bed consolidation, so as to save the cost and time of dredging soil and rocks. "In-situ mixing method" uses the method of immediate excavation, instant mixing, and immediate use. The excavated soil and stone are directly mixed with cement on the construction site, and water is gradually added to mix until it is visually uniform. It can be directly used for backfilling and can provide erosion resistance. Mixing materials for improving structural safety and local strength considerations. In this study, the soil collected on site was used for indoor mixing experiments, and the improvement effect of the site mixing method was verified by numerical simulation analysis.
