摘要
利用浅层地震技术和深孔波速测试技术,结合工程地质勘察和地质钻孔资料对沪闵路高架桥工程场地作地基评价。认为场区基岩面离地表约240米;梅陇一邓镇断裂穿越沪闵路高架二期工程场址,不属新构造运动期的活动断裂构造。在Ⅶ度地震条件下,地表以下20米范围内不会出现液化和震陷灾害。
This paper used earthquake technology of shallow layer and measuring technology in single hole combining means of engineering geological A structure in Humin road . It is about 240m from surface of basement rock to the earths surface, Meilong rift crosses engineering site of Humin road viaduct ,which is not belong to mobile fit structure. The site soil didnt need to be considered about liquefied phenomena and subsidence problem which caused by the condition of grade Ⅶ earthquake intensity.
