地下结构专业抗震计算软件的开发与应用
|
摘要
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。
As to the difficult issues in underground structure seismic design applied response displacement method and response acceleration method such as determining ground motion parameters,calculating soil layer seismic response and setting boundary conditions,a professional seismic analysis software named SAUS is developed using VC + +,which is oriented to the underground structure of road tunnel,subway tunnel,immersed tube tunnel and subway station,etc. The SAUS software consists of four parts,including interface platform,pre modeling processor,seismic solver,as well as result post processor. Pre processor can finish auto-modeling rapidly,set unit attribute,apply load and set boundary condition,etc.The most common circular or rectangular structure can be automatically calculated by seismic solver according to response displacement method and response acceleration method. Post-processing provides structure displacement and internal force contours,result data inquiry and auto-generating calculations,etc. The SAUS software has been applied in many domestic subway design cases and greatly improved the working efficiency of underground structure in seismic design.
