On Establisment of Proper Subtense Length and Side Offset in the Process of setting out, Underground Circular Curve

Tian Linya (Hehai University, Nanjing, 210098)  
Based on the special location of underground circular curve, ways to fix proper subtense length touching underground circular curve are brought forward here, from which the formula of calculating side offset inside and outside a pemissive point of a subtense is obtained, which can guarantee the accuracy of angular and side surveying as well as the speed and quality of construction.
