新疆巴楚地震液化宏观现象的对比分析
|
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。
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 compared with those in the Tangshan earthquake and the Haicheng earthquake. The results show that the liquefaction macro-phenomena of the Bachu earthquake are much different and worthy of more research.
