Application of the Multielememt Composite Ground to Treat Plain Fill/Wang Shuguang,Ye Yan(Institute of Foundation Engineering,China Academy of Building Research,Beijing 100013,China)
Abstract:Multielement composite ground has been used widely in engineering.The design methods of both bearing capacity and settlement are summarized.The bearing capacity testing method is put forward,and the application of the multielement composite ground to treat fill is introduced.The engineering practice illustrates that the requirements of both bearing capacity and settlement can be achieved,and the technique effect and economy profits can be got by using the multielement composite ground in similar engineering.
Keywords:multielement composite foundation; ground treatment; plain fill; bearing capacity; testing method
