| 摘 要： | 本文针对震害预测中的普通场地，讨论了与之有关的震害影响问题。基于ＧＢＪ１１—８９规范所给地震影响系数曲线，这里讨论并得到了不同场地的地震抗力调整系数。它们与一些经验或统计的系数相近，但与之比较，场地因素的调整作用增强。初步应用表明，这个结果更接近实际，且对工程选址和勘探有一定参考价值。

| Abstract: | In the light of the common sites in seimsic hazard, this paper discussed the concerned seisimc hazard influence problems. Based on the seismic influence coefficient curves by the GBJ 11-89 regulation, the adjustment coefficients of seismic resistance for different sites have been discussed and obtained, which are approximate tosome experience and statistical ones and have more powerful adjustment function. This result is more close to the practical situation and has a certain reference value for engineering site option and exploration. |
