1) perinatal injuries
围生期损伤
1.
②The leading disease cause was perinatal injuries,54 cases suffered from this,occupying 58.

2) perinatal damage
围生期损害
3) damage area
损伤范围
1.
Effect of the initial geo-stress unloading on the circular tunnel boundary is studied,and the damage area is calculated by use of combined method of theoretical analysis,numerical simulation by Dynamic FEM and verification with field monitoring vibration data.
计算结果表明在高地应力条件下进行爆破开挖时,初始应力动态卸荷在岩体中所产生的损伤范围比准静态卸荷所产生的损伤范围要大;侧压力系数λ和极角θ是影响初始应力动态卸载应力场的两个主要因素;在一定的卸载速率条件下,侧压力系数λ越大,动态卸载效应越显著,其所产生的损伤范围也相应较大。
2.
The damage area induced by dynamic unloading during blasting excavation is larger than that induced by static unloading during TBM excavation.
因此,初始应力动态卸荷(钻爆开挖)在岩体中所产生的损伤范围比准静态卸荷(TBM开挖)所产生的损伤范围要大;在中高地应力条件下,初始地应力瞬态卸荷所引起的围岩损伤是总体开挖EDZ的重要组成部分。
