Problems solved by technology

In addition, the above-mentioned methods often use the Delphi method to determine the evaluation index system and its weight, so that the final evaluation results are mostly based on the judgment of decision makers, rely too much on the experience of experts, and cannot avoid subjective arbitrariness. lead to inconsistent results

Embodiment Construction

[0154] When the method of the present invention is used, the operation process is as follows.

[0155] Step 1: Analyze and categorize the types of existing weak foundations, treatment plans, and treatment effects, and form a preliminary source example library of soft foundation treatment methods, through the analogy between the target example and source example of the soft foundation treatment plan , According to the degree of similarity between the soft foundation treatment target example and the soft foundation treatment source example obtained by calculation, the preliminary treatment method of the soft foundation treatment target example is obtained. include:

[0156] Step 1.1, classification of soft foundation treatment methods.

[0157] Step 1.2, the establishment of the soft base processing source sample library.

[0158] Step 1.3, data normalization processing.

[0159] Step 1.4, calculate the similarity between the target example and the source example.

[0160] Step 2: Use th...

Abstract

The invention discloses an evaluation method for a soft foundation treatment scheme. The method comprises the following multiple steps of: a. classifying whether soft soil is subjected to shallow, medium and deep treatment by applying a case-based reasoning technology; b. determining an evaluation index system with a Delphi method; c. obtaining an evaluation index weight with a combined weighting method combining an entropy weight method with an analytic hierarchy process; d. screening evaluation indexes by applying fuzzy cluster analysis; and e. calculating a grey evaluation weight by applying grey correlation analysis in a grey theory, establishing a fuzzy weight matrix and calculating a final evaluation result with a fuzzy comprehensive evaluation method. According to the method, different theories and methods are applied in links of evaluation work, so that the defect of excessive dependence on expert experience in a conventional evaluation method for a soft foundation treatment scheme is overcome, both expert opinions and actual situations can be reflected, and the reliability of a comprehensive evaluation result is high.

Description

Technical field [0001] The invention belongs to the technical field of design scheme evaluation methods, and specifically relates to a method for evaluating design schemes used for soft foundation treatment. Background technique [0002] Because soft soil has the shortcomings of high natural water content, high compressibility, low shear strength, and large natural void ratio, improper handling will seriously affect the safety and stability of highways. With the large-scale construction of highways in our country, the problem of soft soil foundation treatment encountered in the project has become more and more prominent. How to deal with soft soil foundation reasonably and effectively has become a key issue in highway construction. [0003] The prerequisite for the reasonable and effective treatment of soft soil foundation is to choose a reasonable and effective soft foundation treatment design plan. Whether the plan is selected properly will have a great impact on the cost, constr...
