| 摘 要： | 2003年2月24日新疆巴楚-伽师地区发生6.8级地震,出现了唐山、海城地震后近30年我国最具规模的砂土液化现象。本文通过现场调查和资料分析,并与以往大地震液化比较,提出了此次地震液化宏观现象的认识,包括液化分布特征、喷水冒砂形态、液化震害和工程地质条件等几个方面。结果表明,此次地震液化宏观现象与我国以往几次大地震有很多不同,具有很大的研究价值。

| Abstract: | On February 24th, 2003 an earthquake of Ms6.8 hit the Bachu-Jiashi area in Xinjiang and caused extremely severe soil liquefaction in recent 30 years after the Tangshan earthquake and the Haicheng earthquake. After in-situ investigation and documented data analysis, this paper presents the understanding of the liquefaction macro-phenomena including liquefaction distribution, sandboils and waterspouts, liquefaction hazard and engineering geotechnical site conditions for the Bachu earthquake. These aspects are... |
