The direction which is the most susceptible to horizontal earthquake action is perpendicular to the bridgeaxis.
水平地震作用的最敏感方向垂直桥的轴线。
2
It demands no circumstance requirements in common optical axis and is especially effective in flexibility measurement of bridge and cloverleaf junction.
该方法无需共轴光路的测量环境要求,特别适用于桥梁、高速公路立交桥的静载挠度测量等工程应用。
