摘　　要：毛里求斯巴加泰勒(BAGATELLE)水坝采用天然高含水率火山灰质土料填筑。在介绍天然高含水率火山灰质土料的物理力学性质的基础上,通过对土料开采、运输、摊铺、碾压等一系列施工措施的研究,总结出在施工过程中降低含水率的方法。实际施工压实效果满足设计要求。The Bagatelle Dam project in Mauritius is filled with natural high moisture content volcanic ash soil material. Based on the physical and mechanical properties of volcanic ash soil material, a series of construction technologies such as soil material mining, transportation, paving and rolling are studied, and the methods to reduce water content in construction process are summed up. The actual compaction effect meets design requirements.
