There are a great many of tunnels in high-grade highway, it is necessary to adopt the small clear distance tunnel.
小净距隧道的主要特点是比分离式隧道占地少，比连拱式隧道造价低，造型美观；但施工难度大，技术含量高。
The blasting construction of small clear distance tunnel inevitably causes accumulative damage of surrounding rocks and its mechanical behaviors will be degenerated.
小净距隧道的爆破施工不可避免地造成围岩累计损伤，岩体力学性能劣化。
Just to be clear, I am putting the maximum acceleration in for a. Also, I have made the assumption that the stopping distance (s) is small compared to the jumping height.
需要声明的是，在上述表达式中，我用a表示跳楼者的最大加速度。此外，我还假设跳楼者完全停下所经过的距离与整个下落距离相比可以忽略不计。
