| 摘 要： | 本文根据南京及周围地区的地震环境，采用概率法对南京河西地区某高层公寓工程场址进行了地震危险性分析，采用等效线性化模型考虑场地土的非线性特性的影响，并用一维波动模型进行了场址土层地震反应和场地地震动效应分析，给出了５０年超越概率６３％，１０％和３％的场址基岩和地表的水平向加速度反应谱值加速度。

| Abstract: | Considering the seismic environment of Naming city and its neighboring area, theseismic hazard for the site of a high-rise building (living quarters) in Hexi area of Naming cityis analyzed by the known probabilistic method, and considering the effect of soil nonlineardynamic property based on equivalent linearization model, the site effect and earthquake response of soil layers are also analyzed by one-dimensional wave motion model, design groundmotion parameters of site for exceedance probability 63, 10 and 3 per cent in fifty years aregiven in this paper. These parameters include horizontal acceleration response spectra and peakaccelerations of base rock and free field ground surface. The results show that the basic intensity of site is equal to seven. The parameters can be used in design of earthquake engineering inthe site district, and they are also useful to the design of earthquake engneering in other siteof Hexi area, Naming city. |
