Verification of Current CPT-Based Liquefaction Evaluation Method by Bachu Earthquake Data

Abstract:

Cone Penetration Test (CPT) has been conducted at 39 liquefied and non-liquefied sites following the Xinjiang Bachu Ms6.8 earthquake. The current CPT-based liquefaction evaluation method, including Chinese code method, the Robertson method and the Olsen method, was verified by those 39 field test data. The results show that the success verification ratio of Chinese code method, the Robertson method and the Olsen method are relative low by using Bachu earthquake data. Many observed liquefied sites were predicted as non-liquefaction sites, which indicate it is progressive to apply those three methods at Bachu area. The characteristic of soils retrieved from Bachu area is quite differ from that of other areas. An appropriate local method of liquefaction evaluation in Xinjiang region should be developed.
