The salon, a three-seater, must've been a front for other things, because it remained hidden way out on two-lane Pick Road, which dead-ended at a creek that fed the Savannah River.

这家只有三座的沙龙一定只是什么东西的前部，因为它一直隐藏着，远离两车道的皮克路——一条汇入萨瓦那河的小溪的尽头。

The results show that tectonic stresses have influence upon the bearing capacity, the destruction form, and the surrounding rock displacement rule of three lane road tunnel.

研究结果表明，构造应力对三车道公路隧道的承载能力、破坏形态、位移规律都有很大影响。
