【摘要】 在上海地铁四号线抢险工程中,综合工程物探快速、准确地圈定了受地面沉降影响,周边土体的扰动范围及深度,并对江底隧道的状况进行了调查。文章介绍了用地质雷达、高分辨率SH波浅层反射波法、瞬态瑞雷面波法勘探及水上高密度多波列地震影像法等综合工程物探方法在该工程中的应用前提及效果。更多还原

【Abstract】 In the Shanghai Subway No. 4 line relieving engineering, integrated engineering exploration bounded the disturbed surrounding soil rapidly and accurately, which is caused by the ground sinking, and surveyed the state of the tunnel under the bottom of river.In this paper ,the application premises and the results of integrated engineering exploration methods , including ground penetrating radar, high differentiation SH wave shallow reflection ,transient Ravleigh wave exploration, high density multiwave seismic photography on the water, are introduced in this engineering.更多还原
