  4. Whether the earth dam lapses in seismic response analysis is mainly judged by two criterion, the damage value and the permanent displacement, so the difference of response between multi - point input and one - point input, that is the multi - point effect, is also checked by this two criterion. therewith the method to calculate damage value and permanent displacement is studied too. the multi - point input is two directional, one direction is along river, and another is vertical

    由於土石壩在地震作用下的失效形式包括累積損傷破壞和過大的永久位移，本文從累積損傷和永久位移兩方面研究土石壩多點輸入相對單點輸入地震反應有何不同，即多點效應如何，因此與多點輸入分析相關的損傷值和永久位移的計算方法也在研究之列。
  5. If the inputted accelerations are velocity - zeroized and the damage value is calculated according to shear stress " extrema, as to 100 - meter - high earth dam, multi - point effect is not distinct ; but as to 240 - meter - high earth dam, in the part where permanent displacement and damage value is originally bigger the response is less tenser than that by one - point input, and in the part near basement the maximal shear stress and damage value is bigger, that is the multi - point effect in time domain

    若同時進行了多點地震動速度歸零化和採用基於極值的損傷值計算方法，對於100米高的土石壩，多點輸入與單點輸入反應十分接近。對於240米高的超大型土石壩，壩體內永久位移和損傷值較大的部位多點輸入的反應量較小，這是多點輸入反應的特點或說多點效應。另外，多點效應也包括壩基部位的最大動剪應力和損傷值偏大這一效應。
