坝顶 [
bà dǐng]
dam crest
- 地震造成的水平加速峰值是从大坝坝基向坝顶急剧增加的。
PHGAs are amplified from the base of the dam to the crest. - 在水库蓄满水的时候,正如人们所预料的,坝顶加速峰值会更大一些。
Peak accelerations, as expected, at the crest are greater with full reservoirs. - 在两个案例中,这种峰值增加只是在坝顶测量到的加速峰值为2.0g(美国帕克伊马拱坝为2.3g),而日本家所重力坝坝顶的加速峰值为2.05g。
In two cases, this amplification produced measured peak accelerations at the crest in excess of 2.0 g (Pacoima arch dam – USA (2.3 g) and Kasho gravity dam – Japan (2.05 g)).
