Abstract
To address the engineering challenges of intense rainfall and shortage of construction materials in the Tropical Rainforest Region of Fiji,a study on the adaptability of local backfill materials was carried out based on the Fiji Water Supply Project and the Waila Pipeline Project.By comparing existing available local materi-als,an innovative proposal was made to use locally available soapstone as backfill for pipeline trenches and road subgrades.The dynamic cone penetration(DCP)testing method was employed to accurately control the depth of foundation treatment,while field tests were conducted to determine the construction techniques and optimal parameters for common materials in Fiji.Engineering practice has demonstrated that soapstone fill exhibits ex-cellent stability,effectively controls post-construction settlement,and outperforms conventional earth fills with less sensitivity to rainfall.This technology ultimately improved construction efficiency by approximately 30％and reduced costs by about 88％compared to graded crushed stone(AP65),successfully resolving quality and cost control issues in fill construction under high-rainfall conditions.It provides a reliable technical refer-ence and practical example for similar regions.关键词
