江西多雨季节路堤填筑施工关键技术与实施要点

Key Technologies and Implementation Points for Embankment Filling Construction during Rainy Seasons in Jiangxi Province

摘要: 江西多雨季节导致路堤填料含水率严重超标，削弱压实度与密实度，并因基质吸力丧失大幅降低土体抗剪强度，显著增加边坡失稳和工后沉降风险。针对此，永新东绕城项目提出并应用“系统排水–精准控水–快速压实–成型层防护”一体化技术体系。实践表明，该体系有效维持了高压实合格率，控制了工后沉降，为雨季施工质量与效率矛盾提供了系统性解决方案。

Abstract: During the rainy season in Jiangxi, the moisture content of embankment fill materials severely exceeds the standard, weakening the compaction and compactness, and significantly reducing the shear strength of soil due to the loss of matrix suction, significantly increasing the risk of slope instability and post construction settlement. In response to this, the Yongxin East Ring Road project proposes and applies an integrated technical system of “system drainage - precise water control - rapid compaction - forming layer protection”. Practice has shown that this system effectively maintains the high pressure acceptance rate, controls post construction settlement, and provides a systematic solution to the contradiction between construction quality and efficiency during the rainy season.
