Abstract: The test and study of the foundation bearing capacity are of realistic sigenifcance in full use and tapping of the potential of the foundation bearing capacity,reasonabe selection of the foundation bearing stratum, improvement of the quality of exploration work,and development of the techniques of geotechnical exploration. The systematic discription of the test and study process of the foundation bearing capacity at the site of blast furnace No.2 of Tangshan Iron Steel Co.LTD. And a test technique for the study has been applyed. It is the lab simulation Loading test.
