摘　　要：对UCODE软件进行编程二次开发,建立该软件与有限元软件间接口,实现UCODE程序与有限元软件间的实时数据交换.以浙江某穿山隧道为工程背景,进行围岩弹性力学参数反演程序验证.以隧道围岩弹性模量E及泊松比v为待反演参数,弹性模量E反演初始值分别设定为真值的1/2和2倍,泊松比v反演初始值作相应变化.反演分析结果表明,无论待反演参数初始值如何取值,反演结果都收敛于真值附近,且与真值误差不超过3%,验证了反演程序的稳定性和精确性.According to secondary development in UCODE software,the interface between finite element softwareand UCODE was established,which achieved real-time data exchange between them.Based on the mountain tunnelexcavation engineering in Zhejiang province,inversion analysis was conducted for identifying estimated mechanicsparameters of surrounding rock in the tunnel.This paper focused on two elastic mechanics parameters,elastic modulusE and Poisson’s ratio v.The initial values of estimated mechanics parameters were set to group1and group2,whichcould reflect the impact of initial values on the results.The results show that the inversion values converge to thesame set of the values and the evaluated value errors are less than3%,which verify the stability and accuracy ofthe inversion program.
