| 摘 要： | 笔者利用单孔波速测试技术,对上海市区区域工程场地作稳定性地质调查与评价。其评价指标主要为场地土类型及场地类别、场地液化势和场地地脉动卓越周期。资料表明,市区-15m范围内区域工程场地土类型属软弱场地土,为Ⅳ类建筑场地;市区南部的场地地脉动卓越周期约为0.65s,北部可达0.8s,其它区域仅为0.7s;市区西南部和苏州河流域在Ⅶ级地震条件下极易产生液化。

| Abstract: | Using the technology for measuring single hole wave speed, the author made geological surrey and stability evaluation of regional engineering sites in the urban district of Shanghai. The evaluation parameters mainly include soil type of the site, category of the site, liquefying power of the site, and remarkable cycle of site pulsation. The regional engineering site within the city limits permitted by -15m belongs to the wear site, being of Grade IV building site. The remarkable cycle of site pulsation is about 0.65 s in the south of the city proper, about 0.8s in the north of the city proper, and 0.7s in other areas. The southwestern urban area and the Suzhou River valley are liable to suffer from liquefying if Grade VII earthquake should occur. |
