Research on Stability Evaluation of Large Area Soft Soil Foundation Treatment Based on Fuzzy Comprehensive Evaluation Method
The stability of soft soil foundation is the key factor of engineering safety in the process of foundation treatment of large area blow fill,so it is very important to evaluate the stability of foundation in the phase of blow fill loading and the pre-loading stage after loading.The factors that affect the stability of the foundation are not only random,but also fuzzy.Select some factors that have significant influence on the stability of the foundation,establish the hierarchical structure model,determine the weight matrix of the evaluation index,and use the fuzzy comprehensive evaluation method to construct the classification model of the stability of the foundation.This model is applied to a blow fill treatment project to evaluate the stability of soft soil founda-tion in the process of blow fill,and the evaluation results are basically consistent with the field practice.
