    • Abstract
  • In 2003, a large-scale liquefied phenomenon occurred in Bachu-Jiashi region of Xinjiang due to an earthquake of Ms6.8, 39 in-situ CPT data are collected from the liquefied liquefied sites. Since the existing CPT-based prediction methods for soil liquefaction are not applicable to Bachu region of Xinjiang, a new evaluation formula is proposed based on the measured data of cone tip resistance value, ground water level, sand burial depth and intensity. The evaluation method is divided into the initial evaluation and the next evaluation. The evaluation success ratio is 95% in liquefied sites and is 94% in non-liquefied sites. The results show that the model has high reliability. The form of the proposed formula is in accordance with that of the most commonly-used liquefaction formula in China. The new formula may provide technical support for prediction of soil liquefaction in Xinjiang and relate areas.
