There is the largest scale infrastructure in the world to
have been building in China in recent 20 years
我国重大工程建设的宏大规模已居世界之首
 A lot of infrastructure have been built
已经建成一大批重大工程
上海金茂
南京长江三桥
国家大剧院

6
of
highest
buildings
in
the
world,
492m
大厦
世界前10座最高建筑,我国6座 (492m)
 7 of largest span cable-suspended bridges in the world, 1088m
世界前10座最大跨度斜拉桥,我国7座 (1088m,在建)
 3 of largest suspended bridges in the world, 1490m
世界前10座最大跨度悬索桥,我国3座 (1490m)
 The largest
hydraulic project in the world: The Three Gorge
三峡大坝
秦岭隧道
Project
世界上最大规模的水利工程——我国三峡工程
 The highest dam in the world: 292m, 305m
世界上最高的拱坝——我国小湾(292m)、锦屏(305m)
 And more infrastructure to have been building or to be built,
such as the highest building, TV tower, dam and the largest span
cable-suspended bridges
正在或将要建设更多的重大工程
——世界上最高的建筑、电视塔、拱坝以及跨度最大的斜拉桥等
上海环球 广州

The infrastructure to be built each year
in China exceeds the summation of all
other countries in the world
小湾大坝
我国每年以土木水利工程为主的基础设施建
设规模已经超过世界上其他所有国家的总和
The objective: Facing 1000m-span bridges, 500m-height
tall buildings, 300m-hight dams
Key issues: Simulation and verification of Strong earthquake
and typhoon fields
Simulation and verification of nonlinear dynamic
damage and collapse of infrastructure
Failure model optimization and control of
infrastructure
面向重大工程——千米级大桥、五百米级超
高层建筑、三百米级高坝等
聚焦重大科学问题
——强地震动场和强／台风场模拟、集成与验证；
重大工程结构构件、结构整体及其耦合介质的非线性动力损伤演化与灾变过程模拟、集
成与验证；
重大工程结构动力灾变的失效机理、失效模式优化与灾变控制
Simulation, analysis and design of civil infrastructure under
strong earthquake or wind could be realized
not only possibly, but also more accurately and more finely
•
How to get more accurate action and models of strong earthquake ground
motion and Hurricane velocity fields?
•
How to establish the fine computational models of infrastructure such as huge
bridges, buildings and dams?
•
How to numerically, physically or hybridly simulate the damage evolution and
collapse process of infrastructure such as huge bridges, buildings and dams?
•
How would the properties and models of structural materials, members and
systems effect on the damage evolution and collapse process of
infrastructure such as huge bridges, buildings and dams?
•
How to improve and even optimize or control the damage evolution and
collapse modes of infrastructure such as huge bridges, buildings and dams?
