| 摘 要： | 基于温州典型软弱土地基上修建国家储备粮库的工程实践,结合现场监测结果,进行复合地基沉降常规方法和有限元数值计算,研究了加筋垫层对水泥搅拌桩地基沉降和桩土应力分担比的影响,分析了水泥搅拌桩联合加筋垫层加固软土地基性状。实践表明,采用本文方法较好地解决了大跨度粮库的地基沉降与不均匀沉降问题,可为相关工程提供借鉴。

| Abstract: | Based on the practice of soft ground treatment by using composite foundation of deep mixing cement piles and geotextile-reinforced cushion at Wenzhou Grain Depot, some results of the in-situ test and the numerical analysis were presented. Influences of the geotextile-reinforced cushion on settlement and stress ratio of pile-soil were discussed. It was shown that problems of settlement and unusual settlement of grain depot on soft ground could be solved by this kind of foundation treatment method. It could be further applied to relevant projects. |
