强震裂谷区隧道及大跨桥场地潜在断错位移预测
Prediction of Potential Dislocation for Tunnel and Long Span Bridge Sites in Strong Earthquake Rift Valley Areas
摘要
Abstract
The fracture design parameters of linear engineering(railway and high way),intersected by faults includes the fault distribution and fault activity mode,the width of fracture zone,the possibility of future destructive earthquake and the average displacement of single event.Take two projets with a lot of active faults as Ngong Tunnel of kenya Naima Railway and DK40 Bridge for example,and based on the principles of correlation,structural anal-ogy and safety,the potential fault displacement of single event of active fault across tunnels and bridge sites is pre-dicted,The distribution of faults,the mode of fault activity,the width of fracture zone and the possibility of future destructive seismic events are also discussed and analyzed.The example has a high reference value for obtaining the anti-fracture design parameters of linear engineering crossing active faults in strong seismic areas of Pacific Rim.关键词
