衰減前向波 的英文怎麼說
中文拼音 [shuāijiǎnqiánxiàngbō]
衰減前向波
英文
decreasing forward wave-
Through analyzing bed ' s response to wave, in the condition that super - stratum is more hard and second - stratum is more soft in region of interest, super static interstitial hydraulic pressure amplitude die away rapidly between stratums, before in sight of boundary between hard and soft stratum, plane effective pressure increase to max. shear stress reach peak value when bed thickness is approximately 2. 7 meters, then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity, so the boundary is the most destroy plane on engineering. on the basis of reconnaissance in situ, in normal situation of sea, the structure slides to the basin along the boundary
通過對底床在波浪下的響應分析，對于研究區底床上層較硬而第二層較軟的情況，超靜孔隙水壓力幅值在層間交界處迅速衰減，在臨近硬、軟地層交界處前，水平有效應力增至最大，剪切應力在底床厚度大約2 . 7米左右達到峰值，然後減小，到硬、軟層土交界位置，達到最小，因此這個界面就是最容易發生破壞的工程軟弱面，現場勘查證明，即使在正常海況下，構築物也會沿坡以此交界面為滑動面，緩慢向「盆」底滑動。2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures, and s - waves attenuate more rapidly in rocks with water - filled fractures. 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves. 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions
結果表明： 1 ）平行排列裂縫造成的各向異性使波前變寬； 2 ）含乾裂縫巖石對波型轉化的影響比含充水裂縫巖石的大，橫波在含充水裂紋中傳播時衰減較快； 3 ）當介質存在各向異性時，爆炸點源產生的波不僅有縱波，還有橫波； 4 ）通過改變點源函數研究不同點源所產生波以及波型的轉換。
