针对深基坑支护方案优选因素具有模糊性的特点 ,依据模糊数学原理建立了深基坑支护方案优选的综合评价模型 ,其指标体系由技术可行、工期节省、经济合理、质量与安全可靠 4个方面构成。应用该综合评价模型 ,结合工程实例对深基坑支护方案进行了排序 ,为深基坑支护方案的选择提供科学的理论依据。
Based on the fuzzy characteristics of the optimization factors of the deep foundation pit support scheme, a comprehensive evaluation model for the optimization of the deep foundation pit support scheme was established based on the principle of fuzzy mathematics. The index system was technically feasible, the construction period was saved, the economy was reasonable, and the quality and safety were reliable. It consists of 4 aspects. Applying this comprehensive evaluation model, the project plans for deep foundation pit support are sorted out in combination with engineering examples to provide a scientific theoretical basis for the selection of support plans for deep foundation pits.
