The location of auxiliary drainage systems in a field is mechanically designed based on field preparation information. [Solution] The auxiliary drainage design method (S1) includes an acquisition step (S11) of acquiring the boundary line of the target field, a cut-and-fill construction map showing the extent of cut and fill of the field, and the location of the field's drainage outlet; a reference drainage line generation step (S12) of searching for the longest straight line from the drainage outlet location to the boundary line and generating it as a reference drainage line; a first auxiliary drainage line generation step (S13) of rotating the reference drainage line by a predetermined angle with respect to the reference drainage line centered on the drainage outlet location to generate a first auxiliary drainage line from the drainage outlet location to the boundary line; and a second auxiliary drainage line generation step (S14) of generating a plurality of second auxiliary drainage lines from the reference drainage line to the boundary line, taking into account the extent of the fill.

This invention relates to the field of railway subgrade design, specifically to a railway subgrade design method and apparatus based on a rule engine. The method includes acquiring basic engineering data of the railway subgrade design section, including slope height, soil type, cut and fill type, and groundwater depth; performing rule matching processing on the basic engineering data using a preset design rule library to obtain candidate design schemes; calculating multi-dimensional indicators based on the candidate design schemes to obtain evaluation indicator information corresponding to each candidate design scheme; performing weight adaptive configuration processing on the evaluation indicator information corresponding to each candidate design scheme based on the basic engineering data to obtain an evaluation indicator weight vector; and performing multi-objective optimization decision processing based on the evaluation indicator weight vector and the evaluation indicator information to obtain the railway subgrade design scheme. This invention comprehensively improves the intelligence level and decision quality of railway subgrade design.
