摘要
为有效预防道路地面塌陷事故的发生,需采用有效探测方法查明道路地下土体中存在的空洞、脱空等地面塌陷安全隐患。地球物理探测方法广泛应用于地面塌陷的隐患探测中。利用探地雷达法为主,地震映像法及瞬态面波法为辅的综合物探技术,来探测上海市闵行区某道路地下病害体的基本情况,推测判断病害体性质、深度及影响范围,通过钻探验证探测结果,并对探测到的病害体进行风险评价,为后续工程治理提供物探依据。
In order to effectively prevent road surface collapse accidents,it is necessary to use effective detection methods to identify the presence of voids and cavities in the underground soil of the road,which pose a safety hazard for ground collapse.Geophysical exploration methods are widely used in the detection of ground collapse and cavity hazards.This study uses a comprehensive geophysical exploration technology,mainly using ground penetrating radar,supplemented by seismic imaging and transient surface wave methods,to investigate the basic situation of underground diseases in a certain road in Minhang District,Shanghai.It infers and determines the nature,depth,and scope of the diseases,verifies the detection results through drilling,and conducts risk assessment on the detected diseases,providing geophysical basis for subsequent engineering treatment.
