They ensure the accuracy and reliability of the survey data. Traverse Closure Error The closure error of a traverse is the difference between the calculated coordinates of the starting point and the ending point of the traverse. It is expressed in terms of linear distance and angular error. Linear Closure Error: Linear closure error is calculated using the following formula: Linear Closure Error = sqrt((dx)^2 + (dy)^2) where: dx = difference in x-coordinates between the starting and ending points dy = difference in y-coordinates between the starting and ending points Angular Closure Error: Angular closure error is calculated by summing the angles of the traverse and subtracting it from the expected sum. For a closed traverse, the expected sum is 360 degrees. Adjustment of Errors Once the closure error is determined, it needs to be adjusted to ensure that the traverse closes. There are several methods for adjusting errors, but the most common is the Bowditch method. Bowditch Method: In the Bowditch method, the adjustment is proportional to the length of each traverse leg. The adjustment for each leg is calculated using the following formula: Adjustment for leg = (Closure Error / Total Length of Traverse) * Length of Leg The adjusted coordinates of each point are then calculated by adding or subtracting the corresponding adjustment to the unadjusted coordinates. TBM RL Error Calculation The TBM RL (Reduced Level) error is the difference between the calculated RL of a Temporary Bench Mark (TBM) and its known RL. It is calculated using the following formula: TBM RL Error = Calculated TBM RL - Known TBM RL The TBM RL error is used to assess the accuracy of the leveling survey. Additional Considerations The accuracy of the traverse depends on the precision of the measuring instruments used. The closure error should be within the specified tolerance limits. If the closure error is excessive, the survey should be repeated. It is important to document all calculations and adjustments for future reference. By following these steps and considerations, you can ensure the accuracy and reliability of your traverse calculations and adjustments.
