Finally, we present an arithmetic of multiplehypocentral, heterogenous dislocation, and a multirupture segment superposition model for simulating the earthquake deformation field. The simulated LOS interferometry map presents the distribution characteristics of the earthquake deformation field better than that of previous studied. Meanwhile, a suit of fault geometric parameters of the earthquake is also obtained by the study. Having a better effect upon simulating asymmetry, great dislocation, macro rupture field, and nonhomogeneity of dislocation than the traditional model, the multisegment method is a progress of this work. It provides a better explanation for the study on hypocentral parameters.

基于上述原因，本文对Okada线弹性位错模型的算法进行了改进，提出了"多震源、非均一位错分量、多破裂段叠加"的线弹性模型，该模型模拟出的形变场干涉纹图较好地体现了地震形变场的分布特征，并由此获得了一套较为完整的地震发震断层的几何学特征参数，为破裂带长度、破裂面方向、破裂面大小等震源破裂特征参数研究提供了较好的解释。

The Taichung Domain was moving northwestwards before the 1999 Chi-Chi earthquake: in the footwall of Chelungpu Fault the slip rate was ~10 mm/yr, while in the hanging wall the rate increased eastwards up to 10-30 mm/yr. Two years prior to the earthquake, in the footwall of Changhua Fault the deformation direction changed from WNW to almost due N, and velocity gradient changed from increasing northwards to increasing eastwards, suggesting possible precursor of a large earthquake.

中部地区在集集地震前大致向西北方向位移，车笼埔断层下盘位移速率约在10 mm/yr左右，断层上盘往东侧逐渐增大，在10~30 mm/yr之间；集集地震发生前2年，彰化断层下盘的位移方向由西北西转为偏北的位移型态，位移速度则由南向北增大，转为由西向东增大的趋势；即位移方向与位移速度有明显的改变，可能为地震前兆的相关资讯。

As for coseismic deformation of Chi-Chi earthquake, the footwall of Chelungpu Fault moved southeastwards 0.3-1.5 m, and the value was increasing toward the fault; the hanging wall moved northwestwards 1.4-7.0 m, but the value was smaller south of the Choshui River. After the Chi-Chi earthquake, the hanging wall of Chelungpu Fault was still moving west-northwestwards and kept uplifting, while the footwall gradually changed direction from ESE to WSW or even WNW, clockwise resuming to inter-seismic deformation pattern. It is interesting to notice that despite the largest coseismic deformation in the northernmost segment of Chelungpu Fault, the post-seismic deformation peaked around the epicenter of Chi-Chi earthquake.

集集地震之同震变形，在车笼埔断层下盘向东南方向位移0.30~1.5 m，且越靠近断层位移量越大；车笼埔断层上盘则向西北方向大幅位移约1.4~7.0 m，浊水溪以南的位移量较小；集集地震以后之震后变形型态，以车笼埔断层为分界，上盘在震后向西北西方向位移的型态仍与同震时相同，下盘由同震时一致性的向东南东方向，逐步向西北西或西南西方向位移，亦即在车笼埔断层下盘有逐步依顺时针方向回归至震间的滑移型态；另就位移速率而言，虽然同震变形最大地区在车笼埔断层北端，但其震后的变形量最大地区，却集中於震央位置附近；就地震循环而言，震后的6年期间仍处於地层压密重整阶段，尚未回归至该区震间阶段的位移状态。

When we saw babies died in earthquake,a great number of people died in earthquake,when we saw gruesome sight in earthquake,the tears kept falling and falling.but we do know,the natural disaster is pitilessly,people''s heart is hot,disaster just can make our heart hotter and more stronger!

看着那逝去的孩子们的照片，看着地所有地震中受难人的照片，看看那些触目惊心的场面，眼泪决堤！大自然的灾难是无情的，但我们的心是火热的，无情的灾难只能让我们的心更火热更坚强！

So,how to determine precursory clustering earthquake and how to fully utilize it to forecast earthquake and to monitor earthquake activity need to be deep studied and probed.

所以，如何判定前兆震群和充分利用前兆震群预报地震和监视未来地震活动有待更深入的研究和探讨。

To associate aseismic design idea that"no damage under light earthquake, reparable under medium degree earthquake and no collapse under intense earthquake"with design method based on damage property, the thesis adopted different damage limit values to control structural damages at different levels so that the designed structure can embody the substantial need of aseismic design based on damage property.

把"小震不坏、中震可修、大震不倒"的抗震设计原则与基于损伤性能的方法统一起来，采用不同的损伤容限值来限定各水准下的结构损伤，从而使所设计的结构充分体现基于损伤性能抗震设计的实质要求。

Steel moment-resisting frames with welded beam-to-column connection were traditionally regarded as having excellent performance, and widely adopted in steel constructions, but this opinion changed after the 1994 Northrige earthquake and the 1995 Hyogoken-Nanbu earthquake. These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure. So it can reduce the damage, and is one of the best choices for resisting earthquake.

Tertiary waves are seismically generated acoustic waves that can propagate over great distances in the SOund Fixing And Ranging channel. On 2004/12/26, big Sumatra earthquake ( Mw =9.3) occurs at the Sumatra island. A huge tsunami excited by the energy from the big Sumatra earthquake causes a great lose, thus a lot of scientists from all over the world pay a lot attention to such big Sumatra earthquake.
