In order to efficiently complete the tunnel construction and measurement in unfavorable conditions, a quick and easy measurement checking method is needed. According to the threedimensional coordinates of any point on the working face measured by total station, CASIO measurement program can exactly work out the overbreak and underbreak volume of any point on the working face. This measurement method has low cost, but high convenience in the setting out, measuring and rechecking of tunnel crosssections. The exact and abundant measurement data guide the tunnel construction efficiently. This measurement method can also be used as a rechecking method for other tunnel measurement and construction technologies.
