【摘要】：為了研究地震烈度與峰值加速度(PGA)、峰值速度(PGV)之間的定量關(guān)系,收集了中國(guó)28次地震、美國(guó)52次地震、伊朗9次地震、墨西哥8次地震中的強(qiáng)震動(dòng)臺(tái)站記錄及其對(duì)應(yīng)的震后調(diào)查烈度資料,采用箱線圖檢驗(yàn)基礎(chǔ)數(shù)據(jù)中的離群值,通過(guò)層次分析法設(shè)置權(quán)重的加權(quán)最小二乘法回歸得到Ⅴ≤I≤Ⅸ烈度區(qū)內(nèi),烈度與PGA、PGV的定量關(guān)系分別為:I=3.73log PGA-1.23;I=3.61log PGV+2.72。從Ⅴ度至Ⅸ度,其烈度與PGA的關(guān)系是烈度表中各值的1.5倍至1.1倍左右;與PGV的關(guān)系是烈度表中各值的1.3倍至1.1倍左右。本文統(tǒng)計(jì)的烈度與PGA、PGV之間的轉(zhuǎn)換關(guān)系可供我國(guó)地震災(zāi)害評(píng)估以及抗震設(shè)計(jì)等參考。
[Abstract]:In order to study the quantitative relationship between seismic intensity and peak acceleration (PGA), peak velocity (PGV), 28 earthquakes in China, 52 earthquakes in the United States and 9 earthquakes in Iran were collected. Strong seismic stations recorded in eight earthquakes in Mexico and their corresponding post-earthquake investigation intensity data, using box charts to test outliers in the basic data. Through the weighted least square regression of the weight set by the analytic hierarchy process (AHP), the quantitative relationship between the intensity and PGA,PGV is obtained in the intensity region of V 鈮，
