摘要：In order to solve such problems as ground subsidence, water and mud bursting and shield machine foundering in subway construction which are caused by water-rich karst geological conditions, complete technological process is established to detect and treat karst in urban areas. The occurrence of natural electric field frequency selection method and groundwater determine groundwater occurrence vector that karst and fault fracture zone, and make use of the grouting technology of karst fracture with the treatment. The construction of Yingwanzhen Stationon Changsha Metro Line No. 4 provesthe favorable effect of the detection technology and treatment measures, which provides experience and reference for the construction of Changsha subway and underground engineeringin other cities with water-rich karst areas.
