ON THE APPLICATION OF COMPREHENSIVE FOUNDATION TREATMENT UNDER COMPLICATED CONDITIONS

Under complex terrain and formation condition, the use of single foundation treatment measures is often difficult to meet the requirements of building foundation bearing capacity and deformation coordination at the same time. This paper, taking a foundation treatment project of Beijing Changping district as an example, analyzes the selection methods and thoughts of foundation treatment under complicated conditions, introduces the processing method using two or more foundation treatment technology, discusses the advantages, disadvantages and its application in the engineering characteristics of the foundation treatment measures such as CFG pile, ground replacement and foundation weakening. Based on the summary of the engineering monitoring data analysis, this paper draw a conclusion that comprehensive foundation treatment technology in selection of reasonable conditions could give full play to all kinds of treatment measures, it could also effective coordinating and controlling building deformation and saving the project cost.
