随着地基处理技术的不断发展,新的施工方法不断涌现,其中强夯置换法于80年代后期在深圳某工程首次应用并取得了成功。此次模型试验和现场试验结果,为强夯置换法的应用奠定了基础。目前,深圳在强夯置换法的应用上积累了丰富的经验。本文在此基础上,结合工程实例对强夯置换法的施工、设计及复合地基的承载力标准的确定进行了阐述,提出一些可供实际工程设计、施工、检测参考的经验。
With the continuous development of foundation treatment technology, new construction methods are emerging. Among them, Dynamic Replacement Method was applied for the first time in a project in Shenzhen in the late 1980s and achieved success. The model test and field test results laid the foundation for the application of dynamic compaction displacement method. At present, Shenzhen has accumulated a wealth of experience in the application of dynamic compaction replacement method. Based on this, the construction, design of dynamic compaction displacement method and the determination of bearing capacity of composite foundation are described in combination with engineering examples. Some experiences for practical engineering design, construction and testing are put forward.
