| 摘 要： | 以四川省若尔盖花湖湿地整治工程实例为基础,利用GEO-SLOPE有限元分析软件,建立了天然地基和采用不同松木桩桩间距的地基护堤计算模型.采用邓肯-张模型模拟护堤和地基的本构关系.通过数值计算,分析了护堤的应力和位移变化情况,并对比不同松木桩桩间距模型的受力特征,得出满足沉降和地基承载力要求的最优桩间距.

| Abstract: | For the Zoige Flower Lake Wetland Regulation Project in Sichuan province, by use of GEO-SLOPE fi- nite element analysis software, dike calculating models were set up respectively for natural foundation and founda- tion with timber-piles of different pile spacing. Duncan-Zhang model was used to simulate the relationship between dike and foundation. Based on the results of calculation, the authors analyze the stress and displacement of dike, compare the stressing characteristics of models with different pile spacing before the authors put forward the opti- mum spacing up to the requirements for settlement and foundation bearing capacity. |
