| 摘 要： | 本文基于模糊数学理论,建立深基坑施工对周围环境影响的模糊综合评判模型,对基坑工程的安全性进行评价。以基坑开挖过程中的监测资料为依据,运用模糊综合评价法对监测数据进行量化分析,给基坑周边环境评定综合安全等级。实践证明该方法能够较真实地反映深基坑的风险状况,减少主观判断带来的差异,使评价结果更加精确,为工程的顺利开展提供可靠的保证。

| Abstract: | A response of around surrounding to an adjacent deep foundation pit safety risk fuzzy synthetic evaluation model was established by according to the basic principle of fuzzy math.Based on the monitoring data of the deep foundation pit,the monitoring data was evaluated quantitatively by using the method of fuzzy synthetic evaluation,and then safety grades of foundation can be determined.The result proves that the method can reflect the risk condition of deep foundation pit and reduce the errors caused by subjective judgment.The assessment makes the evaluation results accurate and could guarantee the development of the project. |
