土层地震反应分析中不同参数的敏感性分析

Sensitivity of Different Parameters Applied in Seismic Analysis of Multi-layer Soil Models

土层地震反应分析通常涉及众多的参数 ,正确评价主要参数的离散性和随机性对计算结果的影响 ,是地震影响小区划和地震安全性评价工作可靠性的保证。通过逐个改变输入参数来分析这些参数对计算结果的敏感性 。

Numerous parameters are involved in multi-layer soil response analysis. Correctly evaluating the influence of discreteness and random of these parameters on the analysis results ensures the reliability of seismic zoning and seismic safety evaluation. The values of some parameters have been changed to analyze the sensitivity of these parameters to the results of multi-layer soil response analysis, and some useful conclusions achieved.
