摘要
结合某公路复合地基加固工程,对瑞利波测试技术在地基加固效果检测评价进行了研究.利用测试数据,建立了复合地基置换率和有效加固深度、复合地基承载力和复合地基剪切波速的相互关系.结果表明:复合地基有效加固深度和复合地基置换率是直接影响剪切波速和复合地基承载力的两个最重要的因素,应用瑞利波测试技术能较准确地检测复合地基的加固深度.研究成果可为瑞利波测试中的地层参数反演和地基加固效果评价提供依据和借鉴作用.
Combined with a highway project involving the composite foundation reinforcement, Rayleigh wave testing technology is applied in evaluation of composite foundation reinforcement effect. Based on test data, the relation are established between composite foundation replacement rate and effective reinforcement depth, composite foundation hosted force and composite foundation cut wave of mutual relationship. The test results indicate that Rayleigh waves testing technology can produce accurate detection result of composite foundation of reinforcement depth. It is also found that the composite foundation effective reinforcement depth and composite foundation replacement rate are two most important factors governing the velocity of shear wave and composite foundation bearing capacity.
