水泥拌合土在奥运水上公园工程中的应用

含砂量较高的砂质粉土具有压实性差、变形性能差、水力性能差、抗剪强度较低、易发生湿陷等较差的工程性质,因此将其用于结构基底,尤其是涉水结构基底土方回填是一个具有挑战性的技术难题。顺义奥林匹克水上公园工程,通过改善天然砂质粉土工程性质用于动水赛道填筑,针对施工过程中采用的水泥拌合土加固天然土体原理及施工工艺进行了相关阐述,旨在总结经验,供同行工程人员参考和相互交流。

APPLICATION OF CEMENT SOIL IN OLYMPIC ROWING-CANOEING PARK ENGINEERING

Sandy silt having high sand content has poor compactibility, deformability, hydraulic performance, shearing strength and high collapse possibility. So it is a technical challenge to use sandy sih in the structure foundation, especially in the earth backfill of the structure foundation in water. According to the Shunyi Olympic Rowing-Canoeing Park Engineering where natural sandy silt is ameliorated and used in the dynamic water track filling works, the theory and construction technology of using cement soil to reinforce the natural soil are expounded, so as to summarize experiences for references by and communication among engineers in the same field.
