| 摘 要： | 本文根据唐山地区的东、中、西三条剖面上的地震喷砂的物质成分和理化性质等分析,探讨了不同烈度区液化砂土的颗粒成分、化学成分、物理性质及砂颗粒形态等变化规律,并根据这些规律,编制出以物质成分和性质为基础的、具有多种因素的砂土液化判别图。该图可供砂土液化预测、砂土液化研究者参考

CHARACTERISTICS OF LIQUATION OF SON IN THE AREAS WITH VARIOUS INTENSITIES DURING TANGSHAN EARTHQUAKE AND CRITERIA FOR RECOGNITION OF LIQUATION |

| Abstract: | This paper is to discuss the following aspects of liquafied soil in Tangshan, such as its compositions, properties, morphological features and the changeable regularities. Again, it is pointed out that with the increase of earthquake intensity the mean grain size, sorting coefficient, edge-angle-shaped grains, and the maximum and minimum density and Ga-Na ratio are increasing, but the dense degree, content of organic matter, consolidation degree, and the maximum and minimum porosity as well as |
