The survey method of appling the operation mode of conventional leveling to height survey with total station instrument,simply called leveling survey with total station instrument,is flexible in setting station,is of high precision and rapid process,can overcome the restriction of topography to subsidence survey by conventional leveling.The related theoretics and practice indicates that this method can replace the Ⅲ grade leveling survey when survey distance is shorter,and can meet precision requirement of conventional engineering subsidence observation.
