【摘要】 针对我国地震应急指挥和抗震救灾工作的实际需要,运用ArcG IS技术研制了桥梁隧道地震灾情场景模拟系统。基于地震应急基础数据库和设定的地震参数,考虑地震动影响场和不同类型桥梁隧道的抗震性能,可对震前和震后公路桥梁隧道通行能力场景进行较为准确的模拟,亦可为地震现场救援指挥工作提供辅助支持。更多还原

【Abstract】 According to the actual need of China’s earthquake emergency command and rescue,an earthquake disaster scenario simulation system of bridges and tunnels was developed using ArcGIS technology.Based on the city′s basic geographic information data and seismic parameters,and given seismic influence field and different types of seismic performance of bridges and tunnels,this system can more accurately simulate the pre-earthquake scenarios and the disaster scenarios after the earthquake;it can also provide aided support for the rescue and command in the earthquake.更多还原
