摘　　要：为了系统地评估鉴湖停车场区域的岩溶地质特征,为轨道交通的设计与施工提供切实可行的建议,本次研究通过现场地质勘探,对鉴湖停车场站周边的岩石类型、结构特征及水文条件进行详细调查。通过地质钻孔勘探,区内揭露溶洞、溶隙251个,钻孔遇洞率为52.97%,线岩溶率为11.95%,属岩溶强发育区,存在发生地面塌陷的前提条件,可能对地铁施工和运营造成一定不利影响。为此,提出控水、工程加固等防治岩溶塌陷的措施。研究成果将为绍兴市轨道交通系统的安全运营提供基础数据,促进地方交通基础设施的可持续发展。To systematically assess the karst geological characteristics of the Jianhu Parking Station area and provide practical suggestions for the design and construction of the rail transit,this study conducted a detailed investigation of the rock types,structural features,and hydrological conditions around the Jianhu Parking Station through on-site geological exploration.Through geological drilling exploration,251 karst caves and fissures are exposed in the area,with a hole encounter rate of 52.97%and a linear karst rate of 11.95%,indicating a strongly developed karst area.The existence of ground collapse conditions may have certain adverse effects on the construction and operation of the subway.Therefore,measures for preventing karst collapse such as water control and engineering reinforcement are proposed.The research results will provide basic data for the safe operation of the rail transit system of Shaoxing and promote the sustainable development of local transportation infrastructure.
