Base layer depth prediction method and base layer depth prediction system

摘要

PROBLEM TO BE SOLVED: To improve the accuracy of estimated depth of a base layer. SOLUTION: The base layer depth prediction method includes an estimated depth calculation step S30 for calculating an estimated depth of a base layer at a position where a plurality of supports are constructed based on the result of a preliminary survey, and a plurality of supports for the calculated estimated depth. Estimated depth recording step S40 for recording to a recording means having a recording structure that reflects the positional relationship of the body's construction position, and recording the actual depth of the base layer at the construction positions of a plurality of supports found during construction to the recording means. Achievement depth recording step S50 and other creation positions located near the creation position of the actual depth recording target when recording the actual depth, the actual depth is not known, and the actual depth is unknown. The estimated depth is corrected based on the actual depth of the created position of the actual depth recording target, and is reflected in the recording means including the estimated depth updating step S60. This makes it possible to improve the accuracy of the estimated depth of the base layer at the construction position of each support. [Selection diagram] Fig. 2
