摘要:
大里溪水系旱溪上游段观音桥至南阳桥间,“9·21”大地震后,山顶产生严重裂缝,渠道左侧峭壁大量土石崩落,致使山坡地裸露并阻塞河道,不仅加剧坡面之不稳定性,亦窄缩水流之通水空间,其对上游集水区土砂灾害与洪泛影响甚巨。本支流为大里溪主要河川之一,故在复建工法上采100年洪水频率。除配合现场设计河槽断面外,并进行该河段之水理演算,以确保计划堤顶出水高与洪水之安全宣泄。此外,为保持该坡面之稳定性与自然景观,亦对坡面进行稳定分析与绿美化。
Abstract:
A large crack occurred at the top of the hillslope, and several landslides occurred along the Drought River (a tributary of Dali River) between Guan-In Bridge and Nan-Yang Bridge as a result of Chi Chi earthquake on September 2, 1999. The landslide material blocked part of the channel waterway, and the bare surface increased the instability of the hillslope. Drought River, which is a tributary of Da-Li River, is a principal river in Taiwan. Therefore, it is required to use one hundred-year flood in the design of post-earthquake reconstruction. The cross-sectional shape was designed based on the existing geographical condition and the calculation of gradually varied flow to ensure a proper freeboard and the passage of design flood. In addition, the stability and the vegetation were also considered in the project to conserve the stability and the natural landscape of the hillslope.
