摘要
在大厚度回填土场地上建设大型成品油库,采用分层强夯置换法对全场地进行地基处理。为检测地基处理效果分别进行静载荷检测试验和动力触探检测试验,检测结果表明地基承载力和压缩模量参数等指标均能满足设计要求。随后进行油罐充水预压试验和充油过程中的地基沉降观测,观测结果表明工后沉降量均满足设计要求。该地基的处理方法和检测、监测技术为类似场地的地基处理设计和施工提供了参考。
When the large product oil depot project is built on the site with large thickness of backfill,the layered dynamic compaction replacement method is adopted to treat the foundation of the whole site.In order to test the effect of foundation treatment,the static load test and dynamic penetration test are carried out respectively.The test results show that the bearing capacity and compression modulus parameters of the foundation all can meet the design requirements.After that,the oil tank water filling preloading test and the foundation settlement observation during the oil filling process are carried out.The observation results show that the settlement after construction meets the design requirements.The foundation treatment method,detection and monitoring technology provide a reference for similar ground treatment design and construction.
