| 摘 要： | 研究目的:沪杭铁路"平改立"工程新建箱涵桥周边软土地层陆续出现不均匀沉降,塌陷形成土洞,多次进行物探检测,效果不理想,本文旨在充分研究该地区箱涵桥软土地层结构及其沉降成因后,采用地质雷达法、瞬态面波勘察技术进行检测试验研究。研究结论:综合多座箱涵桥的成果分析认为,采用不同于传统面波法的多次覆盖多道瞬态面波进行探测,并采用CMP解析法,可有效地压制干扰波,提高信噪比,在箱涵桥的沉降检测中应用效果良好。

| Abstract: | Research purposes: The uneven subsidence appeared in the soft soil stratum around the newly-built railway box culvert and bridge of Shanghai-Hangzhou Railway and it brought about the earth cavity because of collapse.The geophysical prospecting was conducted for several times,but the results were not good.Based on the full analysis of the structure and the formation cause of the soft stratum around the box culvert and bridge in this area,the experimental study was done on the detection of the subsidence with... |
