| 摘 要： | 在软土地基深基坑开挖支护工程的设计与施工中,岩土体力学参数的取值问题是关键。基于MATLAB(R2007a)模糊工具箱中的自适应神经模糊推理系统(ANFIS)对基坑岩土体力学参数进行了位移反演分析,并结合汉口火车站出站厅基坑工程实例,动态反演了具体参数,检验了反演精度,从而验证了该方法用于基坑工程位移反分析的可行性及工程适用性。

| Abstract: | In the construction and design of the excavation and support of foundation pit in soft soil foundation,the selection of geotechnical physical parameters is the key.Based on the adaptive neuro-fuzzy inference system(ANFIS)of MATLAB(R2007a)fuzzy toolbox and in combination with the foundation pit of the exit hall of Hankou Railway Station,this paper makes a dynamical back analysis of the specific parameters,tests the precision of inversion parameters,and verifies the feasibility and engineering application of the method used in the analysis of the inversion parameters of foundation pit. |
