在采用反应位移法和反应加速度法进行地下结构抗震设计时,考虑到在地震动参数确定、土层地震动反应、边界条件设置等方面存在的复杂性,采用VC++开发面向道路隧道、地铁区间隧道、沉管隧道、地铁车站等地下结构的专业抗震计算软件SAUS。该软件由软件界面平台、建模前处理、抗震计算分析、结果后处理四部分构成。前处理功能可自动快速地完成建模、设定单元属性、施加荷载和设置边界条件等;抗震计算提供常用的多种圆形和矩形结构的反应位移法和反应加速度法的自动计算;后处理功能提供结构的位移和内力云图显示、结果数据查询以及自动生成计算书等。通过实际工程的应用,极大提高了地下结构在抗震设计方面的工作效率。
In the seismic design of underground structures by reaction displacement method and reaction acceleration method, taking into account the complexity of the determination of the seismic parameters, the seismic response of the soil layer and the setting of the boundary conditions, VC ++ was used to develop tunnels for tunnels, metro tunnels , Immersed tunnels, subway stations and other underground structure of the professional seismic calculation software SAUS. The software consists of software interface platform, modeling before processing, seismic calculation and analysis, the results of post-processing four parts. The pre-processing function can automatically and quickly complete the modeling, set the unit properties, apply load and set the boundary conditions; seismic calculation provides a variety of commonly used circular and rectangular structure of the reaction displacement method and the reaction acceleration method of automatic calculation; Functions provide structural displacement and internal force cloud display, query results data and automatically generate calculations and so on. Through the application of practical engineering, the working efficiency of underground structures in seismic design has been greatly improved.
