Re-investigating Liquefaction Case Histories from the 1976 Tangshan Earthquake

摘要：

The authors performed subsurface field investigations at liquefaction/non-liquefaction sites from the 1976 Tangshan Earthquake. These sites were re-investigated because the previous CPT data was collected using a now obsolete cone without sleeve measurements. Sites that experienced high ground shaking intensity and/or contained high fines content were the focus of this investigation. Field measurements were made using the seismic cone penetration test (SCPT) as well as spectral analysis of surface waves (SASW) and subsurface soil sampling techniques. This collaborative effort by researchers in China and the U.S. resulted in increasing the worldwide CPT case history database on the order of ten percent. Preliminary results are presented in this paper.
