工程專家:工法可行 安全可議

中國時報【張朝欣╱雲林報導】

由雲林縣政府辦理的「中國醫藥大學北港分院市地重劃」工程,因擋土牆倒塌,造成2名未滿16歲打工學生1死1傷,外界對於將擋土牆切割後再修復補強的工法有所質疑,檢調將介入調查,不願具名的工程專家說,工法理論上可行,但安全措施可議。

縣府地政處指出,之前承包商施作的擋土牆為一體成型,沒有伸縮縫設計,加上基底不平而傾斜,縣府依合約求償後重新發包,新承包商依設計計畫書,用大型電鋸將擋土牆切割分段,增設伸縮縫後再導正。

工程專家說,此次施工,用切割方式將擋土牆切成小長條,再加以導正,工法應沒有問題,但因切割後傾斜段的擋土牆基底,也同時與未傾斜段擋土牆基底分離而失去支撐力,一旦現場重型機具運作產生震動,便可能傾倒。
