汕尾市区砂土液化分析
|
摘要
采用标准贯入试验法对抽取的汕尾市区34个野外钻孔资料进行液化分析,计算液化指数,判断液化等级,进而划分液化小区。结果表明,汕尾市区滨海堆积平原普遍存在砂土液化地震地质灾害,液化等级轻微、中等至严重均有分布,以中等液化为主。根据建筑物类别和工程建设场地的实际情况提出抗液化措施的建议。
Using standard penetration test, we analyses the field data of 34 bores which was finished in Shanwei City proper, calculate I_(lE), judge liquefying grades, and then divide it into liquefying areas. The result shows that there are many seismological geological disasters of sandy soil liquefaction in the shore cumulate plain of Shanwei City. The liquefying grades are from light to serious, but moderate grate is mainly. The liquefaction-fighting suggestions according to building classification and actual conditions of constructions sites are give at last.
