subface meaning in Chinese
底面
Examples
- Time - domain analysis of irregular wave slamming on subface of open - piled structures
不规则波对透空式建筑物上部结构冲击作用时域分析 - Also the concrete structure ' s service life may be threatened by the negative pressure occurred when waves se parate from the subface of the structures
另外当波浪离开上部结构底面时产生的负压力作用对混凝土结构的耐久性也是一个很大的威胁。 - Under confused sea condition , the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface . previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs , followed by a slowly - varying uplift pressure of less magnitude but of considerable duration , and which typically is first positive , then decreases to zero and becomes negative , in hostile sea state , the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed
若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。 - The incident wave height h1 / 3 is in the range from 0 . 1m to 0 . 25m , and the peak period tp in the range from 1 . 0s to 2 . 0s . the ratio of s / h1 / 3 , which refers to the subface level of wharf deck ( s ) to the incident wave height ( h1 / 3 ) , is between - 0 . 1 and 0 . 7 . three different shore connecting types : open - piled , permeable slope with armored 1ayer of dolosse b locks and impermeable slope with armored layer of concrete plate , are set in the experiment for the research on the effects of boundary condition with different shore connecting types on the wave impact
本文的物理模型试验在大连理工大学海岸和近海工程国家重点实验室的大波流水槽中进行，试验中选用的随机波靶谱为改进的jonswap谱，入射波波高h _ ( 1 / 3 )范围为0 . 1m 0 . 25m ，谱峰周期t _ p范围为1 . 0s 2 . 0s ，码头面板的相对净空(码头面板底面距离静水面的距离s与入射波波高h _ ( 1 / 3 )的比值)范围为- 0 . 1 0 . 7 ，其中s / h _ ( 1 / 3 )为负值时表示码头面板底面位于静水面以下。
