Method and Accuracy of Declivity Survey Based on Total Station Instrument

The building's stability and reliability have become the people's focus along with its continuous hightening and broadening.The inclination is one of the key factors used to judge the construction technique and quality.However,the traditional observation ways,for example,the small angle observation method and transit projection method,as be confined with the instrument's accuracy and surveying condition,can't reach a very high precision.The procedure and method for declivity survey based on the total station instrument are introduced here,then the precision is analyzed.The practical experience confirms that it can predigest the outside works and improve the work efficiency.
