【摘要】 探讨了基于遥感影像图进行城市地震灾害模拟的可行性,提出了一套利用G IS栅格分析功能进行城市地震灾害模拟的方法。详细论述了一种从TM/ETM+遥感影像图提取群体建筑物专题信息并创建群体建筑物栅格的方法,以及场地地震动峰值加速度(PGA)衰减栅格、工程场地条件栅格的创建方法。结合调查资料,对某市群体建筑物进行了基于栅格的地震破坏模拟,得到了可信的地震灾害模拟结果,说明基于栅格分析城市地震灾害具有可行性。更多还原

【Abstract】 This paper discussed the possibility of city earthquake disaster simulation based on RS image and GIS grid analysis.The detail technique of this simulation,including extraction of specialist information of swarm building from Landsat TM/ETM+ image and creating PGA attenuating grid and worksite condition grid has also been discussed in this paper.As an example,the credible earthquake disaster simulation result of swarm building for Qingdao City was provided.It proves that new simulation techniques are feasible.更多还原
